28dec004c0 Do some things to make -ffunction-sections work better.
* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
  so that -ffunction-sections works for those asm file too.

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

dcf442e61f YUV Dither: r12 saving was removed but stacked parameter load offset wasn't changed to compensate, resulting in an improperly aligned dither kernel.

989021ed3c Apply some ARMv6 optimisations to YUV blitting. Speeds up mpegplayer on Gigabeat S by ~2% in undithered and ~7.5% in dithered mode.

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.

adb6a00c59 Update lcd-as-memframe.S to only rotate YUV data for portrait LCDs (and remove the D2's temporary C implementation). Enable MpegPlayer dithering option for D2.

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

287d6223d3 Dithering option for mpegplayer on gigabeat-f/x and e200. Assembly IDCT for ARm just to make it all work more nicely. Move UI simulator YUV code to its core to adapt it.
