f748d3b49f Some more size optimisations, giving a tiny write speedup as well.

3655a32a3e Further MMC driver touchup: * Save a tiny amount of power by not enabling the internal flash clock when accessing the MMC. * R2W factors > 32 are valid in newer MMC specs, so don't limit to 32 anymore. * Revise the port setup, and only do the basic setup once.

e42a7373f6 Fix error handling in multiple block read and multiple block write state. When an error occurs, the host still needs to send CMD_STOP_TRANSMISSION resp. the STOP_TRAN token.

36e311f68b Implement chasing bitswap for reading. Speeds up reading single 512-byte blocks by 15..20%. * Restructure the write buffer handling a bit, making it more readable and a bit smaller. Also fixes an old corner case bug: writing data from address 0x0 (archos boot ROM dump) would have written wrong data.

b1a584a1b6 Simplify & fix the MMC driver. After more than 3 years I found that the MMC specs were a bit misleading, and the 'large' MMC which state a block size of 1024 or 2048 bytes and no partial read and/or partial write capability are happily accepting a block size of 512 bytes. So go KISS and remove all the variable/partial block handling code. This fixes the driver for the Transcend 4GB MMCplus, which doesn't cope when we actually set the 2048 byte block size it states. It also makes write operations involving small blocks faster and more reliable. * Note: The 4GB Transcend still doesn't work when plugged at boot, but works when hotplugged.

a0b5780e2d Remove sector 0 write protection from the ATA and MMC drivers. The one in the ATA driver makes it impossible to change sector 0 from within rockbox USB mode, and nobody reported having seen that sector 0 panic for a loong time. Afaik it dates back to when ATA and filesystem write support were developed.

a9b2fb5ee3 Finally full multicore support for PortalPlayer 502x targets with an eye towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties.

82f9056988 Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly.

shutdown doesnt work. Threads with callbacks must handle these 2 events
instead.

f184152c05 * changes to ata.c - idle callbacks are called after 2 sec of real idle, 
and shutdown and usb (it makes sense here). ata_sleep doesnt get broken
by callbacks.
* allow ata_sleep() at the end of buffering again
* config block uses ata_idle instead of delayed sector when saving
* remove delayed sector code from ata_mmc.c (idle callbacks are not yet
implemented for ata_mmc.c tho)

a85044bf9e New scheduler, with priorities for swcodec platforms. Frequent task 
switching should be more efficient and tasks are stored in linked
lists to eliminate unnecessary task switching to improve performance.
Audio should no longer skip on swcodec targets caused by too CPU
hungry UI thread or background threads.

27abc2a641 (1) Early USB detection on boot, before trying to mount the partitions. Cleaner & quicker; removes the need for the extra USB check at the top of ask_resume() which caused a deadlock in screenshot mode (see patch #1110332). On Ondio, this allows to leave an MMC in the slot when booting with USB connected for instant access. (2) Ondio: Track MMC status, only ask to remove the card if required. Probe MMC status if unknown.
