ca9111ef64 Add KEEP() around vectors in linker scripts.
Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections, 
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.

28dec004c0 Do some things to make -ffunction-sections work better.
* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
  so that -ffunction-sections works for those asm file too.

e62dfa5225 FS#12397 : On targets which load .data directly into its final location and lack code for moving it, remove linker script trick which ignores section alignment and word-aligns the section instead.

1b275d8ddb Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places.

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

ce4da595e1 Gigabeat S: INIT section wasn't properly overlapping the uninitialized areas thus wasn't being reclaimed.

60f843bf18 Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up.

a420561bf8 Gigabeat S: Reclaim about 800K of memory that was laying unused. Get rid of DEVBSS_ATTR for this target and implement as NOCACHEBSS_ATTR. Plugin and codec buffers move so all that is now incompatible (do full update). No version increase for plugins/codecs because the loader will reject them.

e1e8101837 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.

4d3a020f27 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.

2bbacf89fe Make sure the linker considers crt0*.o before all files specified on the command line by using STARTUP() instead of INPUT() in the .lds. Using INPUT() makes the linker process crt0*.o after all files specified on the command line, making linking fail if there are librockbox.a members which are only referenced by crt0*.o. Remove the hackaround that was needed for building the gigabeat S bootloader before (aka UIE() problem).

7a2d9ddb08 move some data around to place qh_array at the start of iram. This saves up to about 2k iram on PP

94f7d0f290 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.

feb3b588e3 explicitly align the ibss section by adjusting _iramend - fixes hang on m:robe (and potential problem on other arm targets)

ef62d6891a Split up app.lds to the respective target directories. The portalplayer devices replicate app.lds since their target tree doesn't follow a syntax typical to the newer arm targets - the portalplayers could be cleaned up further. boot.lds and plugin.lds still need to be cleaned up.
