c5a309afbd 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()

06bc627c99 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.

f3857abf6b 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.

9cf5270f10 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())
