[PATCH 0/5] Add the support for MPC8641 silicon rev 2.0 and MPC8641HPCN board 2.0

Hi, Kumar,

This patch is not included in Wade's patch.

MPC8641 silicon 1.0 is end of life and not full following
PCI/PCI-Express specifications.
Rev 2.0 silicon fixes these PCI/PCI-Express errata and follows the
PCI/PCI-Ex specifications.
So, using generic PCI codes is okay.

This's a simple and clear solution to Wade's pci fix patch. Some changes
of Wade's pci fix patch are redundant.

This patch is not included in Wade's patch.

Every PCI hose bus range number is started from 0 before. This patch
make the hose bus range number is started from previous hose last bus
number added one.
And PCI-Ex tranining status check is added to avoid the system halt.

This patch is different than Wade's pci fix patch.
Wade's pci patch changing MPC8641 PCI_CLASS property is not a good
solution. Only set it to transport bridge is okay.
And this quirk functions should applied to both MPC8641 and MPC8641D,
not only dual core version.

This patch is not included in Wade's patch.
It makes IDE in ULI1575 works.

Wade's MTD patch (patch 1), Legacy patch (patch 2), superIO patch (patch
3), RTC patch (patch 4) is not overlap with my patches.
But Wade's PCI patch (patch 5) most of codes is for supporting a
discontinued and end of life silicon and I do not agree with the changes
about PCI_CLASS of MPC8641. The dts fixing is too complex. I suggest to
reject Wade's PCI patch.

Thanks!
