Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

14config MTD_PHYSMAP
15 tristate "CFI Flash device in physical memory map"

17 help
18 This provides a 'mapping' driver which allows the CFI probe and
19 command set driver code to communicate with flash chips which
20 are mapped physically into the CPU's memory. You will need to
21 configure the physical address and size of the flash chips on
22 your particular board as well as the bus width, either statically
23 with config options or at run-time.
24
25config MTD_PHYSMAP_START

30 This is the physical memory location at which the flash chips
31 are mapped on your particular target board. Refer to the
32 memory map which should hopefully be in the documentation for
33 your board.

41 help
42 This is the total length of the mapping of the flash chips on
43 your particular board. If there is space, or aliases, in the
44 physical memory map between the chips, this could be larger
45 than the total amount of flash present. Refer to the memory
46 map which should hopefully be in the documentation for your
47 board.
48 Ignore this option if you use run-time physmap configuration
49 (i.e., run-time calling physmap_configure()).

56 This is the total width of the data bus of the flash devices
57 in octets. For example, if you have a data bus width of 32
58 bits, you would set the bus width octect value to 4. This is
59 used internally by the CFI drivers.

100 System's TS-5500 board. The flash is split into 3 partitions
101 which are accessed as separate MTD devices.
102
103 mtd0 and mtd2 are the two BIOS drives. Unfortunately the BIOS
104 uses a proprietary flash translation layer from General Software,
105 which is not supported (the drives cannot be mounted). You can
106 create your own file system (jffs for example), but the BIOS
107 won't be able to boot from it.

417 other boards via setting of the CONFIG_MTD_CSTM_MIPS_IXX_START/

21The ELAN-104NC has up to 8 Mibyte of Intel StrataFlash (28F320/28F640) in x16
22mode. This drivers uses the CFI probe and Intel Extended Command Set drivers.
23
24The flash is accessed as follows:
25
26 32 kbyte memory window at 0xb0000-0xb7fff
27
28 16 bit I/O port (0x22) for some sort of paging.
29
30The single flash device is divided into 3 partition which appear as separate
31MTD devices.
32
33Linux thinks that the I/O port is used by the PIC and hence check_region() will
34always fail. So we don't do it. I just hope it doesn't break anything.

4 Octagon 5066 MTD Driver.
5
6 The Octagon 5066 is a SBC based on AMD's 586-WB running at 133 MHZ. It
7 comes with a builtin AMD 29F016 flash chip and a socketed EEPROM that
8 is replacable by flash. Both units are mapped through a multiplexer
9 into a 32k memory window at 0xe8000. The control register for the
10 multiplexing unit is located at IO 0x208 with a bit map of
11 0-5 Page Selection in 32k increments
12 6-7 Device selection:
13 00 SSD off
14 01 SSD 0 (Socket)
15 10 SSD 1 (Flash chip)
16 11 undefined
17
18 On each SSD, the first 128k is reserved for use by the bios
19 (actually it IS the bios..) This only matters if you are booting off the
20 flash, you must not put a file system starting there.
21
22 The driver tries to do a detection algorithm to guess what sort of devices
23 are plugged into the sockets.

22The SBC-MediaGX / SBC-GXx has up to 16 MiB of
23Intel StrataFlash (28F320/28F640) in x8 mode.
24
25This driver uses the CFI probe and Intel Extended Command Set drivers.
26
27The flash is accessed as follows:
28
29 16 KiB memory window at 0xdc000-0xdffff
30
31 Two IO address locations for paging
32
33 0x258
34 bit 0-7: address bit 14-21
35 0x259
36 bit 0-1: address bit 22-23
37 bit 7: 0 - reset/powered down
38 1 - device enabled
39
40The single flash device is divided into 3 partition which appear as
41separate MTD devices.

39** The Embedded Systems BIOS decodes the first FLASH starting at
40** 0x8400000. This is a *terrible* place for it because accessing
41** the flash at this location causes the A22 address line to be high
42** (that's what 0x8400000 binary's ought to be). But this is the highest
43** order address line on the raw flash devices themselves!!
44** This causes the top HALF of the flash to be accessed first. Beyond
45** the physical limits of the flash, the flash chip aliases over (to
46** 0x880000 which causes the bottom half to be accessed. This splits the
47** flash into two and inverts it! If you then try to access this from another
48** program that does NOT do this insanity, then you *will* access the
49** first half of the flash, but not find what you expect there. That
50** stuff is in the *second* half! Similarly, the address used by the
51** BIOS for the second FLASH bank is also quite a bad choice.
52** If REPROGRAM_PAR is defined below (the default), then this driver will
53** choose more useful addresses for the FLASH banks by reprogramming the
54** responsible PARxx registers in the SC520's MMCR region. This will
55** cause the settings to be incompatible with the BIOS's settings, which
56** shouldn't be a problem since you are running Linux, (i.e. the BIOS is
57** not much use anyway). However, if you need to be compatible with
58** the BIOS for some reason, just undefine REPROGRAM_PAR.

2 * MTD map driver for BIOS Flash on Intel SCB2 boards
3 * $Id: scb2_flash.c,v 1.11 2004/11/28 09:40:40 dwmw2 Exp $
4 * Copyright (C) 2002 Sun Microsystems, Inc.
5 * Tim Hockin <thockin@sun.com>
6 *
7 * A few notes on this MTD map:
8 *
9 * This was developed with a small number of SCB2 boards to test on.
10 * Hopefully, Intel has not introducted too many unaccounted variables in the
11 * making of this board.
12 *
13 * The BIOS marks its own memory region as 'reserved' in the e820 map. We
14 * try to request it here, but if it fails, we carry on anyway.
15 *
16 * This is how the chip is attached, so said the schematic:
17 * * a 4 MiB (32 Mib) 16 bit chip
18 * * a 1 MiB memory region
19 * * A20 and A21 pulled up
20 * * D8-D15 ignored
21 * What this means is that, while we are addressing bytes linearly, we are
22 * really addressing words, and discarding the other byte. This means that
23 * the chip MUST BE at least 2 MiB. This also means that every block is
24 * actually half as big as the chip reports. It also means that accesses of
25 * logical address 0 hit higher-address sections of the chip, not physical 0.
26 * One can only hope that these 4MiB x16 chips were a lot cheaper than 1MiB x8
27 * chips.
28 *
29 * This driver assumes the chip is not write-protected by an external signal.
30 * As of the this writing, that is true, but may change, just to spite me.
31 *
32 * The actual BIOS layout has been mostly reverse engineered. Intel BIOS
33 * updates for this board include 10 related (*.bio - &.bi9) binary files and
34 * another separate (*.bbo) binary file. The 10 files are 64k of data + a
35 * small header. If the headers are stripped off, the 10 64k files can be
36 * concatenated into a 640k image. This is your BIOS image, proper. The
37 * separate .bbo file also has a small header. It is the 'Boot Block'
38 * recovery BIOS. Once the header is stripped, no further prep is needed.
39 * As best I can tell, the BIOS is arranged as such:
40 * offset 0x00000 to 0x4ffff (320k): unknown - SCSI BIOS, etc?
41 * offset 0x50000 to 0xeffff (640k): BIOS proper
42 * offset 0xf0000 ty 0xfffff (64k): Boot Block region
43 *
44 * Intel's BIOS update program flashes the BIOS and Boot Block in separate
45 * steps. Probably a wise thing to do.

5
6 The VMAx 301 is a SBC based on . It
7 comes with three builtin AMD 29F016B flash chips and a socket for SRAM or
8 more flash. Each unit has it's own 8k mapping into a settable region
9 (0xD8000). There are two 8k mappings for each MTD, the first is always set
10 to the lower 8k of the device the second is paged. Writing a 16 bit page
11 value to anywhere in the first 8k will cause the second 8k to page around.
12
13 To boot the device a bios extension must be installed into the first 8k
14 of flash that is smart enough to copy itself down, page in the rest of
15 itself and begin executing.
