52ed74aad0 mips: Adjust main & irq stack sizes to fit in IRAM on all targets
New amounts:

7.50K main stack
0.75K irq stack

Prior values of 8K+1K overflowed IRAM by ~660 bytes on Onda 7x7 targets,
but worked on the xDuoo X3.

(The discrepancy is due to the Onda targets having more LCD code shoved
 into IRAM.)

36a50dd00f mips: Use a separate IRQ stack & optimize IRQ handling a little
Should prevent the IRQ-related stack overflows seen on MIPS targets.

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.

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

3478bc5d6d mips is predefined by gcc, but we want it for paths. Don't let others fall into this trap again. Use __mips instead

bcb0fc2c12 Allow mkinfo.pl to read the RAM usage correctly. All other targets define both loadaddress and _loadaddress as well.

38436038a9 Ingenic Jz4740:
* Add initial RoLo support
 * Don't enable IRAM in plugins for now
 * Initial try at getting PCM working (doesn't crash anymore at least)
 * Replace hard-coded constant with #define in usb-jz4740
