f504153857 FS#10048 : enable MMU and data cache on Sansa AMS to give a major speed up 
- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)

Before reporting any problem, please check your filesystem or format your player from the OF

308f21dc68 ARM C Runtime : prepare to exception vectors if not in the bootloader 
For example if running from SDRAM, we need to copy the vectors to offset 0

b56b0a37f4 remove dead code from firmware/target/arm/crt0.S, and conditionalise bits of it 
make the meizu builds compile with the new crt0.S location

e0f8c31216 Move the S5L8700 (Meizu) crt0.S file up one level - it can be used as a generic ARM crt0.S (the uncommitted patch for the Sansa V2s uses it).

32f6109fb1 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)

f48e0b514c Gigabeat: Get rid of the obsolete FIQ wrapper (not used on PP anymore FIY, but no change there). Use the FIQ stack for DMA address and size variables instead of globals.
