3a1127785b Bootloader USB mode for PP502x. Enable only on GoGear SA9200 for the time being. Add HAVE_BOOTLOADER_USB_MODE to config if BOOTLOADER is defined to enable it. Clean up some kernel stuff a little to support it. Mess up a bunch of other stuff (hopefully not too badly).

9339be1279 Rework ATA driver to get rid of lots of target-specific constants and allow for non-memory-mapped task file registers.

62321ed0bd Make ATA code not bother to retry requests that return IDNF (specified sector not valid). 
There's no point retrying these requests for five seconds, the sector number isn't going to get any more valid. It interferes with being able to detect broken drives like the 5.5G 80GB iPod's.

533cf7737b Enable ATA DMA on pp5020 based players with ATA drives. 
DMA is only used for reading because writing seems to be slower with DMA.
Only requests which are cacheline aligned (16 bytes) will use DMA, so many
requests will still use PIO at this point; a later change will align more
reads.

Part of FS#9708, original DMA code by Boris Gjenero (dreamlayers).

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

1fbf847eed PP5002 ATA driver needs to wait for the controller to be ready again before writing the next control register value. Makes check_registers() not fail in the bootloader.

174c7abdff Add some new findings to the PP header files. * Clean up ata-target.h for PP. * check_registers() seems to work fine on PP5002.

fe23dc8f15 Improved CPU clock setup for PP502x. PP5020 and PP5022 are not register compatible here, so define the PP5022 targets properly, and introduce a CPU_PP502x macro for easier family check. Improves stability on PP5020 (less freezing, tested with Mini G1) and reduces clock change penalty (500us on PP5020; uses the relock bit on PP5022).

5d51784faa Assembler optimised ATA transfer loops for ARM targets. Only used for PP5020/5021/5022 targets atm. PP5002 seems to have problems with it not directly related to the asm code itself, and the gigabeat doesn't profit from it, probably because the CPU isn't the bottleneck even without optimisation.
