f8edc32589 FS#10756 - Free unused init code
Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

b2323be33b ARM: lr addresses the next instruction after the failing one in undefined instruction vector
Substract 4 before passing the argument to UIE so the correct address is displayed

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

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)
