Cache error exception
(1)When i port mips to r3000.I got the following message:
cp0_errorepc == 00000000
cp0_cacheerr == 00000000
Decoded CP0_CACHEERR: primary cache fault in insn reference.
Error bits:
IDX: 0x00000000
Kernel panic: Can't handle the cache error - panic!
In idle task - not syncing
(2)the cpu has 2k Dcache and 2k Icache.but the r3k_cache_size say it has not any cache.(because it found the cache size> 0x40000 the it let size=0
