Hi Paul !
I've looked at the patch in the meantime and it makes much sense. I want
to do something around those lines:
- Completely rip off CONFIG_ALL_PPC in favor of CONFIG_GENERIC_PPC32
- Each board model has it's own CONFIG_xxx entry (like Michael patch),
which means adding "back" CONFIG_PMAC, CONFIG_CHRP, CONFIG_PREP, but
those will only control which set of .c file will get in the makefile
and the toplevel switch/case on platform_init. That is you will be able
to select an arbitrary set of boards.
- bi_recs are found in r4 when r3 contains "birc" (please, Michael, adapt
to this so we stay consistent which what BootX does). Older way of finding
them & cmdline & initrd still used when r3 doesn't contain that magic
value. r5 still contains the OF PROM pointer, at least until we have
the OF interface in a wrapper.
I think this patch will not be that invasive, and it will be fully backward
compatible, so I do intend to push it to _2_4_devel though I want your
ack first. I don't plan to include Michael boards in it, I want to rework
our ground to match what Michael does and then let him drop in his new
