PCI for mpc8270

PCI for mpc8270

[Chris Simmonds]

Hi,

Can anybody point me to a sample implementation of PCI on an mpc8270?

Thanks,
Chris.

If  mpc8270 has 60x bus,I think you can use CPC710,MV64361....................

The 8270 has the internal PCI bridge, like the 8265/66.
The linuxppc_2_4_devel kernel has the PCI functions and setup
for the 8266 on the Motorola ADS board.  It would be a
starting point for you.

Dan,

Thanks, I have included that code in my kernel and it seems to be
working ok - haven't really tested it yet but at least bus enumeration
works.

This code is based on the PCI 9 workaround for the bug in the 8265,
which uses an IDMA channel for all access. Has anybody looked at doing a
version without the woorkaround? Would it make any difference to the
performance of the system?

Bye for now,
Chris.
