Good point.
There is also IMMR need to be passed from bootloader to kernel.  We 
can make more use of the u-boot bd_info mechanism.  But it binds ppc 
linux to u-boot boot loader.  I don't know if we should make it a 
porting convention.

Well, immr is _already_ part of bd_t passed from U-Boot! I was 
surprised that none of board ports (some of which are made for U-Boot 
only) use this. 

In 8248 based board port I'm working on right now, I already defined 
CPM_MAP_ADDR as follows:

#define CPM_MAP_ADDR            (((bd_t*)__res)->bi_immr_base)
