Hello all,

I'm having a little fun with my first embedded system - it's an
Intrinsyc CerfCube, http://www.intrinsyc.com/products/cerfcube405EP/

basically it's got an ibm 405ep powerpc processor in it.  the thing
ships with a version of 2.4.21 but i've decided to take the newer
kernels for a spin on it.  except i can't compile unless i enable pci,
which is unnecessary for this thing since it has no pci bus.  i've
attached the config in case someone can point out a mistake.  Otherwise
there's a genuine bug in the ppc build for the 405ep in 2.6.7-rc2 and
rc3 - namely that it requires pci.  If no one wiser and more up to speed
on ppc kernel hackery than i (given that all my computers are x86,
getting a cross-compiling toolchain together to even build ppc binaries
was enough of a learning experience for me...) fixes it first, i may
venture in and take a look but i figure it might be faster if one of you
guys went in. ;-)

the error i get from the build is: 

arch/ppc/platforms/4xx/built-in.o(.init.text+0x2e0): In function
`bios_fixup':
: undefined reference to `early_write_config_dword'
arch/ppc/platforms/4xx/built-in.o(.init.text+0x2fc): In function
`bios_fixup':
: undefined reference to `early_read_config_dword'


i knew enough to know that that was pci related, and sure enough the
problem goes away as soon as pci bus support is enabled.  

.config attached

thanks for your time guys,

-aubin


ps -- after briefly looking over the config to attach i noticed that
CONFIG_BIOS_FIXUP=y - what menuconfig option does that correspond to, as
it's probably something i don't need - and i'll bet it makes the problem
go away when you turn it off too huh? sorry for the noise if that's the
case, could someone please educate me slightly?
