1251 | |||
1252 | The MDIO is a bus to which the PHY devices are connected. For each | ||
1253 | device that exists on this bus, a child node should be created. See | ||
1254 | the definition of the PHY node below for an example of how to define | ||
1255 | a PHY. | ||
1256 | |||
1257 | Required properties: | ||
1258 | - reg : Offset and length of the register set for the device | ||
1259 | - compatible : Should define the compatible device type for the | ||
1260 | mdio. Currently, this is most likely to be "fsl,gianfar-mdio" | ||
1261 | |||
1262 | Example: | ||
1263 | |||

2102 | viii) Multi-User RAM (MURAM) | ||
2103 | |||
2104 | The multi-user/dual-ported RAM is expressed as a bus under the CPM node. | ||
2105 | |||
2106 | Ranges must be set up subject to the following restrictions: | ||
2107 | |||
2108 | - Children's reg nodes must be offsets from the start of all muram, even | ||
2109 | if the user-data area does not begin at zero. | ||
2110 | - If multiple range entries are used, the difference between the parent | ||
2111 | address and the child address must be the same in all, so that a single | ||
2112 | mapping can cover them all while maintaining the ability to determine | ||
2113 | CPM-side offsets with pointer subtraction. It is recommended that | ||
2114 | multiple range entries not be used. | ||
2115 | - A child address of zero must be translatable, even if no reg resources | ||
2116 | contain it. | ||
2117 | |||
2118 | A child "data" node must exist, compatible with "fsl,cpm-muram-data", to | ||
2119 | indicate the portion of muram that is usable by the OS for arbitrary | ||
2120 | purposes. The data node may have an arbitrary number of reg resources, | ||
2121 | all of which contribute to the allocatable muram pool. | ||
2122 | |||
2123 | Example, based on mpc8272: | ||
2124 | |||
2125 | muram@0 { | ||
2126 | #address-cells = <1>; | ||
2127 | #size-cells = <1>; | ||
2128 | ranges = <0 0 10000>; | ||

2143 | - #size-cells : Either one or two, depending on how large each chipselect | ||
2144 | can be. | ||
2145 | - ranges : Each range corresponds to a single chipselect, and cover | ||
2146 | the entire access window as configured. | ||

1 | The PowerPC boot wrapper | ||
2 | ------------------------ | ||
3 | Copyright (C) Secret Lab Technologies Ltd. | ||
4 | |||
5 | PowerPC image targets compresses and wraps the kernel image (vmlinux) with | ||
6 | a boot wrapper to make it usable by the system firmware. There is no | ||
7 | standard PowerPC firmware interface, so the boot wrapper is designed to | ||
8 | be adaptable for each kind of image that needs to be built. | ||
9 | |||
10 | The boot wrapper can be found in the arch/powerpc/boot/ directory. The | ||
11 | Makefile in that directory has targets for all the available image types. | ||
12 | The different image types are used to support all of the various firmware | ||
13 | interfaces found on PowerPC platforms. OpenFirmware is the most commonly | ||
14 | used firmware type on general purpose PowerPC systems from Apple, IBM and | ||
15 | others. U-Boot is typically found on embedded PowerPC hardware, but there | ||
16 | are a handful of other firmware implementations which are also popular. Each | ||
17 | firmware interface requires a different image format. | ||
18 | |||
19 | The boot wrapper is built from the makefile in arch/powerpc/boot/Makefile and | ||
20 | it uses the wrapper script (arch/powerpc/boot/wrapper) to generate target | ||
21 | image. The details of the build system is discussed in the next section. | ||
22 | Currently, the following image format targets exist: | ||
23 | |||
24 | cuImage.%: Backwards compatible uImage for older version of | ||
25 | U-Boot (for versions that don't understand the device | ||
26 | tree). This image embeds a device tree blob inside | ||
27 | the image. The boot wrapper, kernel and device tree | ||
28 | are all embedded inside the U-Boot uImage file format | ||
29 | with boot wrapper code that extracts data from the old | ||
30 | bd_info structure and loads the data into the device | ||
31 | tree before jumping into the kernel. | ||
32 | Because of the series of #ifdefs found in the | ||
33 | bd_info structure used in the old U-Boot interfaces, | ||
34 | cuImages are platform specific. Each specific | ||
35 | U-Boot platform has a different platform init file | ||
36 | which populates the embedded device tree with data | ||
37 | from the platform specific bd_info file. The platform | ||
38 | specific cuImage platform init code can be found in | ||
39 | arch/powerpc/boot/cuboot.*.c. Selection of the correct | ||
40 | cuImage init code for a specific board can be found in | ||
41 | the wrapper structure. | ||
42 | dtbImage.%: Similar to zImage, except device tree blob is embedded | ||
43 | inside the image instead of provided by firmware. The | ||
44 | output image file can be either an elf file or a flat | ||
45 | binary depending on the platform. | ||
46 | dtbImages are used on systems which do not have an | ||
47 | interface for passing a device tree directly. | ||
48 | dtbImages are similar to simpleImages except that | ||
49 | dtbImages have platform specific code for extracting | ||
50 | data from the board firmware, but simpleImages do not | ||
51 | talk to the firmware at all. | ||
52 | PlayStation 3 support uses dtbImage. So do Embedded | ||
53 | Planet boards using the PlanetCore firmware. Board | ||
54 | specific initialization code is typically found in a | ||
55 | file named arch/powerpc/boot/<platform>.c; but this | ||
56 | can be overridden by the wrapper script. | ||
57 | simpleImage.%: Firmware independent compressed image that does not | ||
58 | depend on any particular firmware interface and embeds | ||
59 | a device tree blob. This image is a flat binary that | ||
60 | can be loaded to any location in RAM and jumped to. | ||
61 | Firmware cannot pass any configuration data to the | ||
62 | kernel with this image type and it depends entirely on | ||
63 | the embedded device tree for all information. | ||
64 | The simpleImage is useful for booting systems with | ||
65 | an unknown firmware interface or for booting from | ||
66 | a debugger when no firmware is present (such as on | ||
67 | the Xilinx Virtex platform). The only assumption that | ||
68 | simpleImage makes is that RAM is correctly initialized | ||
69 | and that the MMU is either off or has RAM mapped to | ||
70 | base address 0. | ||
71 | simpleImage also supports inserting special platform | ||
72 | specific initialization code to the start of the bootup | ||
73 | sequence. The virtex405 platform uses this feature to | ||
74 | ensure that the cache is invalidated before caching | ||
75 | is enabled. Platform specific initialization code is | ||
76 | added as part of the wrapper script and is keyed on | ||
77 | the image target name. For example, all | ||
78 | simpleImage.virtex405-* targets will add the | ||
79 | virtex405-head.S initialization code (This also means | ||
80 | that the dts file for virtex405 targets should be | ||
81 | named (virtex405-<board>.dts). Search the wrapper | ||
82 | script for 'virtex405' and see the file | ||
83 | arch/powerpc/boot/virtex405-head.S for details. | ||
84 | treeImage.%; Image format for used with OpenBIOS firmware found | ||
85 | on some ppc4xx hardware. This image embeds a device | ||
86 | tree blob inside the image. | ||
87 | uImage: Native image format used by U-Boot. The uImage target | ||
88 | does not add any boot code. It just wraps a compressed | ||
89 | vmlinux in the uImage data structure. This image | ||
90 | requires a version of U-Boot that is able to pass | ||
91 | a device tree to the kernel at boot. If using an older | ||
92 | version of U-Boot, then you need to use a cuImage | ||
93 | instead. | ||
94 | zImage.%: Image format which does not embed a device tree. | ||
95 | Used by OpenFirmware and other firmware interfaces | ||
96 | which are able to supply a device tree. This image | ||
97 | expects firmware to provide the device tree at boot. | ||
98 | Typically, if you have general purpose PowerPC | ||
99 | hardware then you want this image format. | ||
100 | |||
101 | Image types which embed a device tree blob (simpleImage, dtbImage, treeImage, | ||
102 | and cuImage) all generate the device tree blob from a file in the | ||
103 | arch/powerpc/boot/dts/ directory. The Makefile selects the correct device | ||
104 | tree source based on the name of the target. Therefore, if the kernel is | ||
105 | built with 'make treeImage.walnut simpleImage.virtex405-ml403', then the | ||
106 | build system will use arch/powerpc/boot/dts/walnut.dts to build | ||
107 | treeImage.walnut and arch/powerpc/boot/dts/virtex405-ml403.dts to build | ||
108 | the simpleImage.virtex405-ml403. | ||
109 | |||
110 | Two special targets called 'zImage' and 'zImage.initrd' also exist. These | ||
111 | targets build all the default images as selected by the kernel configuration. | ||
112 | Default images are selected by the boot wrapper Makefile | ||
113 | (arch/powerpc/boot/Makefile) by adding targets to the $image-y variable. Look | ||
114 | at the Makefile to see which default image targets are available. | ||
115 | |||
116 | How it is built | ||
117 | --------------- | ||
118 | arch/powerpc is designed to support multiplatform kernels, which means | ||
119 | that a single vmlinux image can be booted on many different target boards. | ||
120 | It also means that the boot wrapper must be able to wrap for many kinds of | ||
121 | images on a single build. The design decision was made to not use any | ||
122 | conditional compilation code (#ifdef, etc) in the boot wrapper source code. | ||
123 | All of the boot wrapper pieces are buildable at any time regardless of the | ||
124 | kernel configuration. Building all the wrapper bits on every kernel build | ||
125 | also ensures that obscure parts of the wrapper are at the very least compile | ||
126 | tested in a large variety of environments. | ||
127 | |||
128 | The wrapper is adapted for different image types at link time by linking in | ||
129 | just the wrapper bits that are appropriate for the image type. The 'wrapper | ||
130 | script' (found in arch/powerpc/boot/wrapper) is called by the Makefile and | ||
131 | is responsible for selecting the correct wrapper bits for the image type. | ||
132 | The arguments are well documented in the script's comment block, so they | ||
133 | are not repeated here. However, it is worth mentioning that the script | ||
134 | uses the -p (platform) argument as the main method of deciding which wrapper | ||
135 | bits to compile in. Look for the large 'case "$platform" in' block in the | ||
136 | middle of the script. This is also the place where platform specific fixups | ||
137 | can be selected by changing the link order. | ||
138 | |||
139 | In particular, care should be taken when working with cuImages. cuImage | ||
140 | wrapper bits are very board specific and care should be taken to make sure | ||
141 | the target you are trying to build is supported by the wrapper bits. | ||

1 | * Freescale Communications Processor Module | ||
2 | |||
3 | NOTE: This is an interim binding, and will likely change slightly, | ||
4 | as more devices are supported. The QE bindings especially are | ||
5 | incomplete. | ||
6 | |||
7 | * Root CPM node | ||
8 | |||
9 | Properties: | ||
10 | - compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe". | ||
11 | - reg : A 48-byte region beginning with CPCR. | ||
12 | |||
13 | Example: | ||
14 | cpm@119c0 { | ||
15 | #address-cells = <1>; | ||
16 | #size-cells = <1>; | ||
17 | #interrupt-cells = <2>; | ||

19 | reg = <119c0 30>; | ||
20 | } | ||
21 | |||
22 | * Properties common to mulitple CPM/QE devices | ||
23 | |||
24 | - fsl,cpm-command : This value is ORed with the opcode and command flag | ||
25 | to specify the device on which a CPM command operates. | ||
26 | |||
27 | - fsl,cpm-brg : Indicates which baud rate generator the device | ||
28 | is associated with. If absent, an unused BRG | ||
29 | should be dynamically allocated. If zero, the | ||
30 | device uses an external clock rather than a BRG. | ||
31 | |||
32 | - reg : Unless otherwise specified, the first resource represents the | ||
33 | scc/fcc/ucc registers, and the second represents the device's | ||
34 | parameter RAM region (if it has one). | ||
35 | |||
36 | * Multi-User RAM (MURAM) | ||
37 | |||
38 | The multi-user/dual-ported RAM is expressed as a bus under the CPM node. | ||
39 | |||
40 | Ranges must be set up subject to the following restrictions: | ||
41 | |||
42 | - Children's reg nodes must be offsets from the start of all muram, even | ||
43 | if the user-data area does not begin at zero. | ||
44 | - If multiple range entries are used, the difference between the parent | ||
45 | address and the child address must be the same in all, so that a single | ||
46 | mapping can cover them all while maintaining the ability to determine | ||
47 | CPM-side offsets with pointer subtraction. It is recommended that | ||
48 | multiple range entries not be used. | ||
49 | - A child address of zero must be translatable, even if no reg resources | ||
50 | contain it. | ||
51 | |||
52 | A child "data" node must exist, compatible with "fsl,cpm-muram-data", to | ||
53 | indicate the portion of muram that is usable by the OS for arbitrary | ||
54 | purposes. The data node may have an arbitrary number of reg resources, | ||
55 | all of which contribute to the allocatable muram pool. | ||
56 | |||
57 | Example, based on mpc8272: | ||
58 | muram@0 { | ||
59 | #address-cells = <1>; | ||
60 | #size-cells = <1>; | ||
61 | ranges = <0 0 10000>; | ||

9 | (typically 0x8afc 0x2). | ||

11 | the r/w bit set to zero. | ||
12 | - #size-cells : Should be zero. | ||
13 | - clock-frequency : Can be used to set the i2c clock frequency. If | ||

15 | The following two properties are deprecated. They are only used by legacy | ||
16 | i2c drivers to find the bus to probe: | ||
17 | - linux,i2c-index : Can be used to hard code an i2c bus number. By default, | ||
18 | the bus number is dynamically assigned by the i2c core. | ||
19 | - linux,i2c-class : Can be used to override the i2c class. The class is used | ||
20 | by legacy i2c device drivers to find a bus in a specific context like | ||
21 | system management, video or sound. By default, I2C_CLASS_HWMON (1) is | ||

1 | * UCC (Unified Communications Controllers) | ||
2 | |||
3 | Required properties: | ||
4 | - device_type : should be "network", "hldc", "uart", "transparent" | ||
5 | "bisync", "atm", or "serial". | ||
6 | - compatible : could be "ucc_geth" or "fsl_atm" and so on. | ||
7 | - cell-index : the ucc number(1-8), corresponding to UCCx in UM. | ||
8 | - reg : Offset and length of the register set for the device | ||
9 | - interrupts : <a b> where a is the interrupt number and b is a | ||
10 | field that represents an encoding of the sense and level | ||
11 | information for the interrupt. This should be encoded based on | ||
12 | the information in section 2) depending on the type of interrupt | ||
13 | controller you have. | ||
14 | - interrupt-parent : the phandle for the interrupt controller that | ||
15 | services interrupts for this device. | ||
16 | - pio-handle : The phandle for the Parallel I/O port configuration. | ||
17 | - port-number : for UART drivers, the port number to use, between 0 and 3. | ||
18 | This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0. | ||
19 | The port number is added to the minor number of the device. Unlike the | ||
20 | CPM UART driver, the port-number is required for the QE UART driver. | ||
21 | - soft-uart : for UART drivers, if specified this means the QE UART device | ||
22 | driver should use "Soft-UART" mode, which is needed on some SOCs that have | ||
23 | broken UART hardware. Soft-UART is provided via a microcode upload. | ||
24 | - rx-clock-name: the UCC receive clock source | ||
25 | "none": clock source is disabled | ||
26 | "brg1" through "brg16": clock source is BRG1-BRG16, respectively | ||
27 | "clk1" through "clk24": clock source is CLK1-CLK24, respectively | ||
28 | - tx-clock-name: the UCC transmit clock source | ||
29 | "none": clock source is disabled | ||
30 | "brg1" through "brg16": clock source is BRG1-BRG16, respectively | ||
31 | "clk1" through "clk24": clock source is CLK1-CLK24, respectively | ||
32 | The following two properties are deprecated. rx-clock has been replaced | ||
33 | with rx-clock-name, and tx-clock has been replaced with tx-clock-name. | ||
34 | Drivers that currently use the deprecated properties should continue to | ||
35 | do so, in order to support older device trees, but they should be updated | ||
36 | to check for the new properties first. | ||
37 | - rx-clock : represents the UCC receive clock source. | ||
38 | 0x00 : clock source is disabled; | ||
39 | 0x1~0x10 : clock source is BRG1~BRG16 respectively; | ||
40 | 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively. | ||
41 | - tx-clock: represents the UCC transmit clock source; | ||
42 | 0x00 : clock source is disabled; | ||
43 | 0x1~0x10 : clock source is BRG1~BRG16 respectively; | ||
44 | 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively. | ||
45 | |||
46 | Required properties for network device_type: | ||
47 | - mac-address : list of bytes representing the ethernet address. | ||
48 | - phy-handle : The phandle for the PHY connected to this controller. | ||
49 | |||
50 | Recommended properties: | ||
51 | - phy-connection-type : a string naming the controller/PHY interface type, | ||
52 | i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id" (Internal | ||
53 | Delay), "rgmii-txid" (delay on TX only), "rgmii-rxid" (delay on RX only), | ||
54 | "tbi", or "rtbi". | ||

7 | the parent type. | ||
8 | - reg : should contain the address and the length of the shared message | ||
9 | interrupt register set. | ||
10 | - msi-available-ranges: use <start count> style section to define which | ||
11 | msi interrupt can be used in the 256 msi interrupts. This property is | ||
12 | optional, without this, all the 256 MSI interrupts can be used. | ||
13 | - interrupts : each one of the interrupts here is one entry per 32 MSIs, | ||
14 | and routed to the host interrupt controller. the interrupts should | ||
15 | be set as edge sensitive. | ||
16 | - interrupt-parent: the phandle for the interrupt controller | ||
