1ba26b8a60 MMC driver: More flexible background copy & bitswap concept, using global variables - slightly less read latency when both partial and full blocks are involved. Some code cleanup.

74875ef37e Speed optimisations: (1) Read, write: Use single/multiple block commands depending on the block count. (2) Write: Combine first partial sector transfer (after caching) & main loop into one block-transfer sequence.

a7f7781dca MMC driver does now handle block sizes != 512 bytes, which is necessary to support cards > 1 GB. Changed error handling to use the same method as other parts of rockbox, allowing to trace the call chain. Long policy, code cleanup.

fe0e368d5c Don't panic on read attempts past end of card, just exit with error. Such can happen when mounting superfloppy MMC, without valid partition table.

4d6e482e56 Some MMCs don't like reading their very last sector with the read_multiple_blocks command, so always read it with read_single_block. Slight optimisation.

a450e34770 Major MMC driver rework: DMA for sector transfers (except for single sector writes), bitswap while DMA transfer is running, optimized SCI handling (back-to-back transfer for polled writes), yield()s once per sector transfer. Speed is now close to the theoretical maximum
