2010-06-11FS#11335 by me: make ARM assembly functions thumb-friendlyRafaël Carré1-4/+4
We can't pop into pc on ARMv4t when using thumb: the T bit won't be modified if we are returning to a thumb function Code running on ARMv4t should use the new ldrpc / ldmpc macros instead of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc} No modification on pure ARM builds and ARMv5+ Note: USE_THUMB is currently never defined, no targets can currently be built with -mthumb, see FS#6734 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657

2007-07-02Improved CPU clock setup for PP502x. PP5020 and PP5022 are not register ↵Jens Arnold1-2/+2
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
2007-01-24Assembler optimised ATA transfer loops for ARM targets. Only used for ↵Jens Arnold1-0/+344
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
