4dbee8a90d ppc4xx: 4xx_pcie: Change CFG_PCIE_MEMSIZE to 128MB on Yucca & Katmai
128MB seems to be the smallest possible value for the memory size
for on PCIe port. With this change now the BAR's of the PCIe cards
are accessible under U-Boot.

One big note: This only works for PCIe port 0 & 1. For port 2 this
currently doesn't work, since the base address is now 0xc0000000
(0xb0000000 + 2 * 0x08000000), and this is already occupied by
CFG_PCIE0_CFGBASE. But solving this issue for port 2 would mean
to change the base addresses completely and this change would have
too much impact right now.

This patch adds debug output to the 4xx pcie driver too.

03d344bb6a ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (3)
(3) This patch introduces macros like SDRN_PESDR_DLPSET(port) to access
    the SDR registers of the PCIe ports. This makes the overall design
    clearer, since it removed a lot of switch statements which are not
    needed anymore.

    Also, the functions ppc4xx_init_pcie_rootport() and
    ppc4xx_init_pcie_entport() are merged into a single function
    ppc4xx_init_pcie_port(), since most of the code was duplicated.
    This makes maintainance and porting to other 4xx platforms
    easier.

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
