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.

68af18a56f x1000: Simplify app linker script
Get the linker to automatically assign load addresses for
the .iram and .tcsm sections. Taken from the i.MX31 linker
script.

4bd97c6535 mips: consolidate exception handling, add exception backtraces
Merge the x1000 and jz47xx exception handling code since they use
the same exception vectors and handlers. The interrupt handler is
now called from the common exception vector, but remains separate
for each board since they have different IRQ layouts.

The new exception handler can provide a stack traceback from the
interrupted code, rather than the (uninteresting) caller traceback
displayed by panicf. This allows you to see what led up to a null
pointer deref or division by zero, which makes it _much_ easier to
track down errors that occur in common leaf functions like strcmp.

8b4949381c x1000: add TCSM section to linker script
This is intended for debugging OF kernel boot problems and has
to be enabled manually at compile time to make it usable.

58225bd2c8 x1000: remove plugin and codec buffers on bootloader
On the bootloader there's no point reserving memory for these,
the only users of codecbuf/pluginbuf are in the apps/ tree.

38eafb60ff x1000: use core_alloc in bootloader for loading rockbox
Using the audio buffer directly is a bad idea because this will
render core_alloc non-functional if load_firmware() writes into
the buffer but then fails, for example on a checksum mismatch.

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.
