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.

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

ef8a7eaf2a Major speedup of the iPod Video LCD driver. The internal update procedure of the BCM chip is now completely shadowed, handled by a tick task as necessary. Also fixes the occasional UI freezes due to stalled BCM updates by re-kicking it after a timeout.

b05066de12 iPod Video: Further optimised LCD data transfer (5..6% speedup, but increase in FPS measured with test_fps is less), making use of the fact that the low address bits aren't decoded by the BCM. Major cleanup of the driver, and introduced register names.

3c1b9d9d70 Assembler optimised lcd_yuv_blit() for iPod Video (Fs #7951 by Andree Buschmann, adapted and separated into an .S file by me).
