also in my embed_config(bd_t **bdp) function (in
arch/ppc/boot/simple/embed_config.c) I see
(and use, that is I have ported this from 2.4 to 2.6):
// timebase_period_ns = 1000000000 / bd->bi_tbfreq;
timebase_period_ns = 320; // value adjusted by hand
Could anyone knowledgeable make a guess why this was done (on 2.4) and would
it be OK to re-use on 2.6 ?
Thanks,
Alex

bd_info structure in the kernel booting code
My board is using:
bd->bi_intfreq = 50000000;
bd->bi_busfreq = 50000000;
While RPX-Lite is using
bd->bi_intfreq = 48000000;
bd->bi_busfreq = 48000000;
Is this what makes RPX-Lite work and my (MPC 880) not ?

The "one, I am using" from my previous e-mail relates to 2.6.10-rc3
My processor is MPC880.

Allegedly - yes (with memory initialization) but ...
both Tom Rini and Steve Blakeslee were able to boot their
RPXLite Variant of 8xx on 2.6.10-rc3 (the one I am using)

Aren't there still generic problems w/ 8xx and 2.6.x?
