The p2020DS, MPC8536DS, MPC8572DS, MPC8544DS boards are capable of
swizzling the upper address bits of the NOR flash we boot out of which
creates the concept of "virtual" banks. This is useful in that we can
flash a test of image of u-boot and reset to one of the virtual banks
while still maintaining a working image in "bank 0".
The PIXIS FPGA exposes registers on LBC which we can use to determine
which "bank" we are booting out of (as well as setting which bank to
boot out of).

We have always mapped at least 16M in the kernel and we have seen cases
with new kernel features that a kernel image needs more than 8M of
memory.

The KSEG1ADDR macro used to be necessary for the RTL8139 Ethernet
driver, but the code that used that macro was removed over a year
ago, so board configuration files no longer need to define it.
The _IO_BASE macro is also automatically defined to 0 if it isn't
already set, so there's no need to define that macro either in the
board configuration files.

We want the outbound PCI memory map to end at the 4G boundary so we
can maximize the amount of space available for inbound mappings if
we have large amounts of memory.
This matches the device tree setup in the kernel for the 36-bit physical
configs for the platforms that have one (MPC8641 HPCN & MPC8572 DS).

The patch adds support for P2020DS reference platform.
DDR3 interface uses hard-coded initialization rather than SPD
for now and was tested at 667Mhz. Some PIXIS register
definitions and associated code sections need to be fixed.
TSEC1/2/3, NOR flash, MAC/SYS ID EEPROM, PCIE1/2/3 are all
tested under u-boot.
