Firmware issue.

The 64-bit bootloader is the right way to go, but unfortunately our MIPS
toolchain (specifically ld/as) won't deal with ELF64.

(I looked at this several months ago -- there's a flag that can be passed to
binutils configure to enable the 64-bit targets, but there were some nasty
conflicts with the build scheme for the native toolchain)

Converting from ELF32 to ELF64 via objcopy won't work, either; the IP30 load
address is firmly in 64-bit space, with no translation to/from the 32-bit
view of address space.
