And I am pretty sure I am missing others: 1) /proc/cpuinfo and some bootinfo.h change (I think these two come from one change) 2) split of cache and tlb files 3) some kind of flush_cache_LSB() routines. > >>discussion or pre-warning.

However, outside all the boards that are in oss tree, I can safely say there are at least twenty MIPS porting efforts going on at various stages. Next time those people sync up with oss, they will find the missing symbol of bus_error_init().

In fact, I start to regret about my first email which now looks a little irresponsible. If anything out of this thread can increase the awareness of open discussion and awareness of the existence of many boards which are not part of oss tree yet, I shall be happy. Jun
