a980d5f869 x1000: Enable support for INIT_ATTR
Enable INIT_ATTR support in config.h. Load init code to the
codec buffer, following the convention used by other targets
that support INIT_ATTR.

e8ad52be94 x1000: Rename crt0 .init sections to .startup
Avoid startup code clashing with the .init section, which is
by convention used for INIT_ATTR code that can be discarded
after app initialization.

603412f447 x1000: Clarify definition & usage of RAM areas
Document what the symbols are supposed to mean, fixup SPL's
usage of DRAM_END which should really be SDRAM_END instead.
No functional changes.

0e1a90ea1d x1000: SPL refactoring
This streamlines the boot code a bit and reduces target specific
boilerplate. The clock init hack used by the bootloader has been
"standardized" and works for the main Rockbox binary now, so you
can boot rockbox.bin over USB without special hacks.

3f26fcf340 FiiO M3K: New bootloader
SPL and UCL-compressed bootloader are now packed into one output,
bootloader.m3k, eliminating the separate SPL build phase.

The Rockbox bootloader now has a recovery menu, accessible by
holding VOL+ when booting, that lets you back up, restore, and
update the bootloader from the device.

15ad1c42db X1000: simplify NAND driver
- Removed unnecessary layers of generic code
- Software ECC is gone since we don't need it now (and maybe not ever)
- Removed bounce buffering, so callers must now align buffers

d5695822a7 MIPS: remove .MIPS.abiflags section
The abiflags data is only used to communicate ABI information to a
program loader -- you can see what info is stored with readelf -A.
Dropping it shaves 24 bytes off of every binary (including plugins).

d6220f618b MIPS: emulate -ffunction-sections with macros in mmu-mips
Using a macro to put each function in its own .icode-based section
allows us to put the functions in IRAM _and_ have linker GC. This
removes a troublesome #ifdef BOOTLOADER_SPL on the X1000 target.

b5558c1cf9 x1000: place SPL's NAND bounce buffers in DRAM
This frees up 2 KiB in the SPL's memory map, leaving more room for code.
