On e500 when we leave the 4k boot page we should use an absolute address since
we don't know where the board code may want us to be really running at.

The current implementation does not set the number of bank address bits
(BA) in the processor. The default assumes 2 logical bank bits. This
works fine for a DIMM that uses devices with 4 internal banks (SPD
byte17 = 0x4) but needs to be set appropriately for a DIMM that uses
devices with 8 internal banks (SPD byte17 = 0x8).

Some patches had inserted warnings into the build:
* mpc8560ads declared data without using it
* cpu_init declared ecm and immap without using it in all CONFIGs
* MPC8548CDS.h had its default filenames changed so that they contained
"\m" in the paths. Made the defaults not Windows-specific (or
anything-specific)

Make the early L1 cache stack region guarded to prevent speculative
fetches outside the locked range.
Use _PHYS defines, not _MEM for cpu-side PCI memory mapped regions.
init.S whitespace cleanup.
Allow TEXT_BASE value to be specified on command line. This allows it
to be set to 0xfffc0000 which cuts the uboot binary in half.
Clear and enable lbc and ecm errors.
Update last_busno in device-tree for pci and pcie.
Remove load of obsolete cpu/mpc85xx/pci.0

Support external interrupts from platform to eliminate system hangs.
Define CONFIG_INTERRUPTS board configure option to enable.
Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC.
Remove extra cpu initialization redundant with hardware initialization.
Whitespace cleanup.
Define and use _START_OFFSET consistent with other processors using
ppc_asm.tmpl
Move additional code from .text to boot page to make room for
exception vectors at start of image.
Handle Machine Check, External and Critical exceptions.
Fix e500 machine check error determination in traps.c
TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.

Calculate the data timeout based on values from the CSD instead of

in BSP 2.0, with one additional fix: the DTOCYC value is rounded up

Instead of always using the largest blocksize the card supports, check
if it can support smaller block sizes and use 512 bytes if possible.
Most cards do support this, and other parts of u-boot seem to have
trouble with block sizes different from 512 bytes.
Also enable underrun/overrun protection.

The update procedure was modified to turn off the USB subsystem
before exit for MCC200 and TRAB. This is necessary as otherwise the

- the patch disables the magic key check for MCC200
- the patch contains the configuration changes made
for the new revision of the board.

The last fdt patch to bootm did board setup based on the address
specified by a prior fdt address command invocation. The bootm
code, as its call to fdt_chosen does, should use the fdt specified
by the user on the bootm command. Note this restores full
functionality for the 8360's existing default boot environment
values, e.g. 'run nfsboot' (i.e. no having to 'fdt addr $fdtaddr'
before booting a kernel).

In the patch titled "Create new fdt boardsetup command..." I removed the
call to ft_board_setup() from the routine fdt_chosen(), but I forgot
to add a direct call back into cmd_bootm.c
This fixes the oversight by adding the direct call to the bootm command.

Previously ft_board_setup() was called by fdt_chosen() which was not
really correctly structured. This splits ft_board_setup() out by creating
a new fdt boardsetup command.
Fix a bug when parsing fdt set command values which have the square
bracket form [00 11 22 33] - the length was updated incorrectly in when
parsing that form.
