5ef27368f1 lcd: fix function name in comments in assembly files (lcd_write_yup_420 instead of lcd_write_yuv420) 2012-01-11 13:14:30 +01:00

45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly
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

47d4c4739b ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. Saves a bit of stack and execution time.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or
later. We still need to hunt down snippets used that are not. 1324 modified

d1e2f5240c c200: First implemention of lcd_yuv_blit(). mpegplayer works now, but speed can be optimized more and dithering is not yet implemented.
