2009-03-05mpc83xx: MPC837XEMDS: Initialize SerDes before negating PCIE reset signalAnton Vorontsov
The SerDes initialization should be finished before negating the reset signal according to the reference manual. This isn't an issue on real hardware, but we'd better stick to the specifications anyway.

2009-01-21mpc83xx: Add PCI-E support for MPC837XEMDS boardsAnton Vorontsov
MPC837XEMDS boards can support PCI-E via "PCI-E riser card". The card provides two PCI-E (x2) ports. Though, only one port can be used in x2 mode. Two ports can function simultaneously in x1 mode. PCI-E x1/x2 modes can be switched via "pex_x2" environment variable. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
2008-10-21mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boardsAnton Vorontsov
The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB, standalone or acting as a PCI agent. User's Guide says: - When the CPLD recognizes its location on the PIB it automatically configures RCW to the PCI Host. - If the CPLD fails to recognize its location then it is automatically configured as an Agent and the PCI is configured to an external arbiter. This sounds good. Though in the standalone setup the CPLD sets PCI_HOST flag (it's ok, we can't act as PCI agents since we receive CLKIN, not PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without any arbiter bad things will happen (here the board hangs during any config space reads). In this situation we must disable the PCI. And in case of anybody really want to use an external arbiter, we provide "pci_external_aribter" environment variable.
