20 * NOTES about DMA transfers:
21 *
22 * controller 1: channels 0-3, byte operations, ports 00-1F
23 * controller 2: channels 4-7, word operations, ports C0-DF
24 *
25 * - ALL registers are 8 bits only, regardless of transfer size
26 * - channel 4 is not used - cascades 1 into 2.
27 * - channels 0-3 are byte - addresses/counts are for physical bytes
28 * - channels 5-7 are word - addresses/counts are for physical words
29 * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
30 * - transfer count loaded to registers is 1 less than actual count
31 * - controller 2 offsets are all even (2x offsets for controller 1)
32 * - page registers for 5-7 don't use data bit 0, represent 128K pages
33 * - page registers for 0-3 use bit 0, represent 64K pages
34 *
35 * DMA transfers are limited to the lower 16MB of _physical_ memory.
36 * Note that addresses loaded into registers must be _physical_ addresses,
37 * not logical addresses (which may differ if paging is active).
38 *
39 * Address mapping for channels 0-3:
40 *
41 * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
42 * | ... | | ... | | ... |
43 * | ... | | ... | | ... |
44 * | ... | | ... | | ... |
45 * P7 ... P0 A7 ... A0 A7 ... A0
46 * | Page | Addr MSB | Addr LSB | (DMA registers)
47 *
48 * Address mapping for channels 5-7:
49 *
50 * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
51 * | ... | \ \ ... \ \ \ ... \ \
52 * | ... | \ \ ... \ \ \ ... \ (not used)
53 * | ... | \ \ ... \ \ \ ... \
54 * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
55 * | Page | Addr MSB | Addr LSB | (DMA registers)
56 *
57 * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
58 * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
59 * the hardware level, so odd-byte transfers aren't possible).
60 *
61 * Transfer count (_not # bytes_) is limited to 64K, represented as actual
62 * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
63 * and up to 128K bytes may be transferred on channels 5-7 in one operation.

11**
12** 5/2/94 Roman Hodek:
13** Added bi_atari part of the machine dependent union bi_un; for now it

15** 26/7/96 Roman Zippel:
16** Renamed to setup.h; added some useful macros to allow gcc some
17** optimizations if possible.
18** 5/10/96 Geert Uytterhoeven:
19** Redesign of the boot information structure; renamed to bootinfo.h again

9 * ColdFire DMA Model:
10 * ColdFire DMA supports two forms of DMA: Single and Dual address. Single
11 * address mode emits a source address, and expects that the device will either
12 * pick up the data (DMA READ) or source data (DMA WRITE). This implies that
13 * the device will place data on the correct byte(s) of the data bus, as the
14 * memory transactions are always 32 bits. This implies that only 32 bit
15 * devices will find single mode transfers useful. Dual address DMA mode
16 * performs two cycles: source read and destination write. ColdFire will
17 * align the data so that the device will always get the correct bytes, thus
18 * is useful for 8 and 16 bit devices. This is the mode that is supported
19 * below.
20 *
21 * AUG/22/2000 : added support for 32-bit Dual-Address-Mode (K) 2000
22 * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
23 *
24 * AUG/25/2000 : addad support for 8, 16 and 32-bit Single-Address-Mode (K)2000
25 * Oliver Kamphenkel (O.Kamphenkel@tu-bs.de)
26 *
27 * APR/18/2002 : added proper support for MCF5272 DMA controller.

296 * The MCF5272 DMA controller is very different than the controller defined above
297 * in terms of register mapping. For instance, with the exception of the 16-bit
298 * interrupt register (IRQ#85, for reference), all of the registers are 32-bit.
299 *
300 * The big difference, however, is the lack of device-requested DMA. All modes
301 * are dual address transfer, and there is no 'device' setup or direction bit.
302 * You can DMA between a device and memory, between memory and memory, or even between
303 * two devices directly, with any combination of incrementing and non-incrementing
304 * addresses you choose. This puts a crimp in distinguishing between the 'device
305 * address' set up by set_dma_device_addr.
306 *
307 * Therefore, there are two options. One is to use set_dma_addr and set_dma_device_addr,
308 * which will act exactly as above in -- it will look to see if the source is set to
309 * autoincrement, and if so it will make the source use the set_dma_addr value and the
310 * destination the set_dma_device_addr value. Otherwise the source will be set to the
311 * set_dma_device_addr value and the destination will get the set_dma_addr value.
312 *
313 * The other is to use the provided set_dma_src_addr and set_dma_dest_addr functions
314 * and make it explicit. Depending on what you're doing, one of these two should work
315 * for you, but don't mix them in the same transfer setup.

2 * Apple Peripheral System Controller (PSC)
3 *
4 * The PSC is used on the AV Macs to control IO functions not handled
5 * by the VIAs (Ethernet, DSP, SCC, Sound). This includes nine DMA
6 * channels.
7 *
8 * The first seven DMA channels appear to be "one-shot" and are actually
9 * sets of two channels; one member is active while the other is being
10 * configured, and then you flip the active member and start all over again.
11 * The one-shot channels are grouped together and are:
12 *
13 * 1. SCSI
14 * 2. Ethernet Read
15 * 3. Ethernet Write
16 * 4. Floppy Disk Controller
17 * 5. SCC Channel A Receive
18 * 6. SCC Channel B Receive
19 * 7. SCC Channel A Transmit
20 *
21 * The remaining two channels are handled somewhat differently. They appear
22 * to be closely tied and share one set of registers. They also seem to run
23 * continuously, although how you keep the buffer filled in this scenario is
24 * not understood as there seems to be only one input and one output buffer
25 * pointer.
26 *
27 * Much of this was extrapolated from what was known about the Ethernet
28 * registers and subsequently confirmed using MacsBug (ie by pinging the
29 * machine with easy-to-find patterns and looking for them in the DMA
30 * buffers, or by sending a file over the serial ports and finding the
31 * file in the buffers.)

4/* Core file format: The core file is written in such a way that gdb
5 can understand it and provide useful information to the user (under
6 linux we use the 'trad-core' bfd). There are quite a number of
7 obstacles to being able to view the contents of the floating point
8 registers, and until these are solved you will not be able to view the
9 contents of them. Actually, you can read in the core file and look at
10 the contents of the user struct to find out what the floating point
11 registers contain.
12 The actual file contents are as follows:
13 UPAGE: 1 page consisting of a user struct that tells gdb what is present
14 in the file. Directly after this is a copy of the task_struct, which
15 is currently not used by gdb, but it may come in useful at some point.
16 All of the registers are stored as part of the upage. The upage should
17 always be only one page.
18 DATA: The data area is stored. We use current->end_text to
19 current->brk to pick up all of the user variables, plus any memory
20 that may have been malloced. No attempt is made to determine if a page
21 is demand-zero or if a page is totally unused, we just cover the entire
22 range. All of the addresses are rounded in such a way that an integral
23 number of pages is written.
24 STACK: We need the stack information in order to get a meaningful
25 backtrace. We need to write the data from (esp) to
26 current->start_stack, so we round each of these off in order to be able
27 to write an integer number of pages.
28 The minimum core file size is 3 pages, or 12288 bytes.
