Jens Arnold	fe23dc8f15	Improved CPU clock setup for PP502x. PP5020 and PP5022 are not register compatible here, so define the PP5022 targets properly, and introduce a CPU_PP502x macro for easier family check. Improves stability on PP5020 (less freezing, tested with Mini G1) and reduces clock change penalty (500us on PP5020; uses the relock bit on PP5022). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13763 a1c6a512-1295-4272-9138-f99709370657	2007-07-02 05:16:40 +00:00
Jens Arnold	5d51784faa	Assembler optimised ATA transfer loops for ARM targets. Only used for PP5020/5021/5022 targets atm. PP5002 seems to have problems with it not directly related to the asm code itself, and the gigabeat doesn't profit from it, probably because the CPU isn't the bottleneck even without optimisation. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12099 a1c6a512-1295-4272-9138-f99709370657	2007-01-24 00:12:08 +00:00
