026f711068 ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (2)
This patch is the first patch of a series to make the 440SPe PCIe code
usable on different 4xx PPC platforms. In preperation for the new 405EX
which is also equipped with PCIe interfaces.

(2) This patch renames the functions from 440spe_ to 4xx_ with a
    little additional cleanup

6efc1fc0b6 [PPC440SPe] PCIe environment settings for Katmai and Yucca
- 'pciconfighost' is set by default in order to be able to scan bridges
behind the primary host/PCIe

- 'pciscandelay' env variable is recognized to allow for user-controlled
delay before the PCIe bus enumeration; some peripheral devices require a
significant delay before they can be scanned (e.g. LSI8408E); without the
delay they are not detected

7f19139389 [PPC440SPe] Improve PCIe configuration space access
- correct configuration space mapping
- correct bus numbering
- better access to config space

Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the
first device on the first bus. We now allow to configure up to 16 buses;
also, scanning for devices behind the PCIe-PCIe bridge is supported, so
peripheral devices farther in hierarchy can be identified.

466fff1a7b ppc4xx: Add pci_pre_init() for 405 boards
This patch removes the CFG_PCI_PRE_INIT option completely, since
it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.

a65c5768e5 ppc4xx: Change SysACE address on Katmai
With this new base address of the Xilinx SystemACE controller
the Linux driver will be easier to adapt, since it can now be
mapped via the "normal" ioremap() call.

490e5730c6 ppc4xx: Fix "bootstrap" command for Katmai board
The board specific "bootstrap" command is now fixed and can
be used for the AMCC Katmai board to configure different
CPU/PLB/OPB frequencies.

ba58e4c9a9 [PATCH] Update AMCC Katmai 440SPe eval board support
This patch updates the recently added Katmai board support. The biggest
change is the support of ECC DIMM modules in the 440SP(e) SPD DDR2
driver.

Please note, that still some problems are left with some memory
configurations. See the driver for more details.
