65f1f5a2c3 Don't copy SB1 cache error handler to uncached memory. 
This may have made sense on a paranoid day with pass 1 BCM1250 processors
that were throwing cache error exception left and right for no good
reason.  On modern silicion that hardly makes sense and the code had
gotten just an obscurity ...

9043f7e95d Sync c-tx39.c with c-r4k.c. 
tx39_flush_cache_range() does nothing if !cpu_has_dc_aliases.  It should
flush d-cache and invalidate i-cache since the TX39(H2) has separate I/D
cache.
