pci on ppc

pci on ppc

[Marco Schramel]

Hi,

my kernel does not boot with the kernel option "CONFIG_PCI". (System MPC8270 (PQ2FADS), 2.4.25 denx kernel, eldk 3.0).
Without the pci option it can boot without problems.
UBoot supports my pci. It shows the bridge and the cards i put in.
What i have to attend in the kernel for the 82xx?

Where the function "m8260_setup_arch()" (m8260_setup.c) is called ?? With the pci option the kernel does not call this function.

Thanks a lot
Marco

I don't know If I understand you right or this is helpful to you, but these
functions are never called directly, but instead in platform_init() function
pointers are stored in the ppc_md struct variable, and this holds true for
m8260_setup_arch() as well (in arch/ppc/kernel/m8260_setup.c):

ppc_md.setup_arch = m8260_setup_arch;


There's always only one platform_init() due to the linking process, so there's
no name clash.

Could you elaborate a bit on your PCI problem anyway? Is your board standard or
custom?

With kind regards,

Try it in the 2.6 kernel and I'll actually try to care. IF you haven't
_already_ got 2.4 working, why in $DEITY's name would you be starting to
use it now?
