Re: [patch] linux: DBE/IBE handling rewrite

[Jun Sun <jsun@mvista.com>]

I suggest we have a function pointer called board_bus_error_init, which is 
initialized to a NULL function.  Any board that wishes to override it can do 
so in <board>_setup() routine.

With more amd more MIPS boards poping up, the more friendly board interface is 
the better.
