6a67707b5e Commit to certain names for cache coherency APIs and discard the aliases. 
Wouldn't surprise me a bit to get some non-green.

90a2671833 i.MX31: Make DMA ISR call loop a bit more efficient.

6920d2b9cd i.MX31: Only include the SDMA code that will be used on the target. Simplify the script selection.

e286b0bbc0 Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout.

60f843bf18 Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up.

a420561bf8 Gigabeat S: Reclaim about 800K of memory that was laying unused. Get rid of DEVBSS_ATTR for this target and implement as NOCACHEBSS_ATTR. Plugin and codec buffers move so all that is now incompatible (do full update). No version increase for plugins/codecs because the loader will reject them.

11cca264ff i.MX31/Gigabeat S: Implement frequency and voltage scaling-- 1.6V for 528MHz, and 1.35V for 264MHz and 132MHz. Keep DPTC overdrive ( > 400MHz) voltage scaling off for now because of uncertainties. Simplify the (working) mess later.

ba71cc540c imx31: Rename clkctl-imx31.* to ccm-imx31.* and move up from ...imx31/gigabeat-s to .../imx31. A bunch more should probably go up a level too.

b7f7655dc2 imx31/mc13783: Do some housekeeping with register macros, function names and other defines. No functional changes (except to alter a couple int priorities).

a1a332e04b Gigabeat S: Implement MDMA and UDMA disk access for bootloader and main binary. Add a needed SDMA API to check channel errors. Increase audio DMA channels' priority as required. Reads and writes measure faster accross all test_disk tests and especially at 4KB and 1MB.

d1adf35e62 Gigabeat S: Switch SSI1 and 2 around so that playback can use the shared peripheral DMA with SSI2 which doesn't require use of the peripheral DMA unit-- SSI2 is mapped to the SDMA core address space. Fix some break keywords in get_script_pc(). Use the patched script for mcu_2_app (BSP appears to have neglected to update that). Use _SHP instead of _SP for shared peripheral constants (consistency).

63404a7d5d Separate running an SDMA channel from resetting it. It should make usage more flexible since resets are needed only before restarting if aborting transfers (because the script is left awaiting requests, not the next start) which PCM does alot of but other things likely won't.

609157a145 Gigabeat S: I never intended to leave the channel context buffer static beyond testing. Correct that.
