7a1aca46a3 Smaller & faster grey blitting on greyscale ipods, based on an idea by Mike Sevakis. ISR speedup on all greyscale iPods except Mini 2nd Gen is ~10%. No speedup on the latter, because the serial transfer is the limiting factor.

47d4c4739b ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. Saves a bit of stack and execution time.

41cd44caa7 Greyscale ipod lcd driver: * Assembler optimised low level functions. PP5002 targets benefit most (lcd_update() speedup >50%, and the greyscale overlay no longer makes mp3 playback skip). * Consistent brace placement style.
