The PCI/PCI-e support for the sbc8548 was based on an earlier version of what the MPC8548CDS board was using, and in its current state it won't even compile. This re-syncs it to match the latest codebase and makes use of the new shared PCI functions to reduce board duplication. It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and similarly it coalesces the PCI and PCI-e mem into one single TLB. Both PCI-x and PCI-e have been tested with intel e1000 cards under linux (with an accompanying dts change in place) Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
