Gigabeat S: Place SDMA code load address starting in uninitialized section address and copy it to the plugin buffer since it only needed very early in initialization. Will save about 6K in RAM.

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.

Enable write buffering for the 1MB device memory section. This means using a different device framebuffer address too. You must update the firmware _and_ bootloader.

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.

Gigabeat S mixer: Make some progress. Get the tick and core sleep working using the AVIC. Redo the startup code to remap from IRAM and not include the lcd driver frambuffer in the remapping (until it can be moved). Clean up LCD driver. For other misc. changes, see the diffs. Now it progresses to ATA init and fails with -11 but without crashing or hanging. Replace all bootloaders.

Gigabeat S memory management stuff.

* Moved crt0.S to imx31 subdirectory, as it was the last target using the unified file.
* DRAM is now remapped to 0x0, facilitating interrupts (which aren't done yet)
