- - The codes wants the MBAR to be set at 0xf0000000 by the bootloader. It's
- mapped 1:1 with the MMU. If for whatever reason, you want to change this,
- beware that some code depends on the 0xf0000000 address and other depends
- on the 1:1 mapping.
- - Most of the code assumes that port multiplexing, frequency selection, ...
- has already been done. IMHO this should be done as early as possible, in
- the bootloader. If for whatever reason you can't do it there, do it in the
- platform setup code (if U-Boot) or in the arch/ppc/boot/simple/... (if
- DBug)
