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.

1b275d8ddb Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places.

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.

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.

4d3a020f27 Gigabeat S: Move the LCD framebuffer address so that DRAM can be mapped flat between physical and virtual addresses. NO BOOTLOADER UPDATE SHOULD BE NEEDED. The firmware image now handles low-level system setup as well.

0218397cf4 Gigabeat S bootloader: 1) Switch order of .vectors to be contiguous with initialized sections. 2) Clean all caches in main before doing anything else because vector copying counts as self-modifying code. Up to v.00000012.

2bbacf89fe Make sure the linker considers crt0*.o before all files specified on the command line by using STARTUP() instead of INPUT() in the .lds. Using INPUT() makes the linker process crt0*.o after all files specified on the command line, making linking fail if there are librockbox.a members which are only referenced by crt0*.o. Remove the hackaround that was needed for building the gigabeat S bootloader before (aka UIE() problem).

fe5a35ce06 Also declare .qharray for the bootloader on imx31. Usb is also supported there...

94f7d0f290 UMS for the Gigabeat S. Bootloader USB mode. Has a couple quirks 1) First plug has problems if cold. Replug if it doesn't connect or not at high speed 2) Linux doesn't like the odd bootable flag value used in the partitions so it won't mount but Windows works. Fix minor OTG driver bugs and clean up device memory handling. Generic name for ARC controller driver.
