66f8fb52a9 */app.lds: remove STUBOFFSET
This is related to gdb, and gdb can only work on SH and ifp
This was mistakenly kept when app.lds was forked for each SoC
Side-effect: fix DEBUG builds when the rockbox binary is expected to
be loaded at the start of DRAM and there is no runtime relocation

02afc271c9 as3525v2: Move codec into iram freeing 1MB for the audio buffer and also a small decoding speedup (iram seems to be 50% faster than dram when boosted and the same when unboosed). 32k is still reserved for the core and can be readjusted if needed. Codecs don't appear to ever need the 1MB (usually <350k only).

2ac962aceb Fix as3525 lowmem targets. They put the init code into the plugin buffer, but some init functions are grabbing it.

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.

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.

bac611868e FS#10114 - Sansa AMS : use IRAM for codecs on >2MB targets Rafaël Carré
Activates IRAM for AMS Sansas to be used by codecs and core. Fixes Reboot-on-mp3 and gives speed up on codecs using IRAM in general.
I've made a change: the core/codec ratio is 0x20000/0x30000 instead of 0x10000/0x40000, 0x30000 is way more than codecs currently use (0x14000 at max) and the core might need more than 0x10000.

6aa807d321 Sansa AMS: PCM driver (FS#9592)
Note that on low memory targets (Clip/m200v4 tested) you will encounter
random crashes. Applying FS#9332 seems to help a lot.
