fd715fa95c as3525*: enable MMU in bootloader
Reserve 1MB of DRAM for loading rockbox and use the rest as BSS
Write sdram setup in assembler and move it to a separate file, together
with MMU init code

02660557ad Fix a bunch of boot.lds files so that they build with newer ld. The stack/bss sections need NOLOAD. otherwise the linker would try to include those into the binary. I don't know why this ever worked with our current ld version.

c2c01ac34c Clip+ boots with iram mapped at 0x0, only the clipv2 is different

12af2926e5 Make Clip+ bootloader build
Now making the Fuzev2 bootloader build should be pretty easy

TODO:
    - write button driver (FlynDice found all buttons already)
    - find button light
    - decide if lcd-ssd1303.c must be modified for Clip+ using SSP or forked
    - check if backlight code works (I copied Clipv2 code)

2392bb4199 FS#10047 : Clipv2
Reuse some code from Clip (LCD) and a lot of code from AS3525
Add a new CPU type : AS3525v2, identical to AS3525 except it's an ARMv5 (arm926-ejs)
SD code still not working
For an unknown reason LCD doesn't work anymore (to be investigated)

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

4633446517 Sansa AMS: Centralise mapping of RAM and IRAM in as3525.h via #defines. This will hopefully make ongoing mmu work easier as less places need to be changed.

4944a1c1e1 Common data must be included in .bss or it won't get zeroed in crt0. Fix the archos self-extractor as well to play safe.

da8bff107e Commit FS#9467 - initial work on port to Sansa Clip by Rafaël Carré and François Dinel. A few cosmetic changes were made by me prior to committing: 1) TAB policing in button-clip.c; 2) Add François Dinel to CREDITS; 3) Add François Dinel as (C) holder in button-target.h (it was previously blank); 4) Add Rockbox header to bootloader/sansa_as3525.c with Rafaël Carré as (C) holder; 5) Change target_id to 50 (next available number) in tools/configure and fixed indentation; 6) Change MODEL_NUMBER in config-clip.h to 50 (next available number); 7) Remove unused in/out macros from system-target.h
