Thomas Martitz 7dd548c697 Speed up the Fuze's LCD by a factor of ~2.1 (lcd_update()) by using 32bit transfers when possible.
Unaligned (to 4byte boundary) and odd (where the amount of data is not an integer multiple of 32bit) are still supported. Even those still have a speedup of >2.

clock-target.h AMSSansa: Add AS3525_DRAM_FREQ as a configurable frequency. Attempts to use PCLK != DRAM still fail but a method is now in place. Default scheme remains 248/62/62. 2009-05-29 20:19:35 +00:00

system-target.h ARM922T's icache isn't coherent with its dcache, so we need to ensure that its flushed before changing codecs. Playback takes care of this for us, but only if we define cache coherency functions. Do that. Also, add a comment explaining that MMU functions need to be included so that other people don't spend hours chasing them in the future. 2009-07-05 01:17:25 +00:00
