Well, what memory region is supposed to sit at 0x80009ff8?  It's hard
to help without some idea of what your BSP code assumes about the
target board; what the code was trying to do at the time (--trace).

See the "*cpu:" tags in the src/mips/*.igen files, the configure.in
target filtering lines, and perhaps some TARGET-run command-line
