rockbox/firmware/drivers/lcd-h300.c, branch master

More exodus to the target tree for ColdFire and a bonus sorting of firmware/SOURCES.

H300, X5: Faster lcd_yuv_blit() using EMAC. Speedup of the function itself at 124MHz: 10.5% on X5, 16.5% on H300. mpegplayer speedup 3..4%

H300: (1) Use DMA for LCD updates, with auto-aligned line reads. Speeds up LCD updates by ~ 75% at 11MHz and 45MHz. Only ~ 11% speedup at 124MHz due to (2). (2) Less aggressive LCD transfer timing at 124MHz. With the previous timing, slightly corrupted display contents was reported, and with DMA transfers at least 4 waitstates are needed to make updates work at all. * A table in system-iriver.c shows settings for all integer multiples of the base clock frequency (info for developers, not yet complete).

H300: * Assembler optimised lcd_yuv_blit(), based on the X5 version. 23..31% speedup in tests depending on video size. * Don't set HORIZ_RAM_ADDR_POS for LCD updates, it's unnecessary. * Started the target tree move for H300 with this.

H300: * Implemented lcd_yuv_blit(). Speeds up video playback by about 7%. No bounds check in lcd_yuv_blit() (by convention), implementations for other targets should be adapted. * Fixed off-by-one bug in lcd_update_rect()

H300: Cut-down LCD init & working display flip.

Removed lcd_roll() and lcd_remote_roll() functions. These functions were not really portable. Removed the only plugin that used lcd_roll(): Oscillograph. Oscilloscope offers everything that oscillograph did and more, in a portable way. * Bumped & sorted plugin API.

H300: lcd_write_data() in pure asm, essentially the same speed as before, but working correctly for all allowed data lengths. Removed RAM waste by declaring inline functions static.

Don't init the lcd twice - once on lcd_init_device and the other one on first call of lcd_enable() (an old, known bug).

Linus, please check whether lcd_enable(true) is still required for the h300 bootloader (lcd_init() calls lcd_init_device())
