This patch enables support for EXT2, and increases the
CONFIG_SYS_BOOTMAPSZ size for the default configuration
of the katmai boards to use them as the RAID-reference
AMCC setups.
EXT2 enabling allows one to boot kernels from the EXT2
formatted Compact Flash cards.
CONFIG_SYS_BOOTMAPSZ increasing allows one to boot the
Linux kernels, which use PAGE_SIZE of 256KB. Otherwise,
the memory area with DTB file (which is placed at the
end of the bootmap area) will turn out to be overlapped
with the BSS segment of the 256KB kernel, and zeroed
in early_init() of Linux.
Actually, increasing of the bootmap size could be done
via setting of the bootm_size U-Boot variable, but it looks
like the current U-Boot implementation have some bootm_size-
related functionality lost. In many places through the U-Boot
code the CONFIG_SYS_BOOTMAPSZ definition is used directly
(instead of trying to read the corresponding value from the
environment). The same is truth for the boot_jump_linux()
function in lib_ppc/bootm.c, where U-Boot transfers control
to Linux passing the CONFIG_SYS_BOOTMAPSZ (not bootm_size)
value to the booting kernel.

modify the CAS timings. my understanding is that these
settings decrease various wait times in the DDR interface.
Because these wait times are in clock cycles, and the DDR
clock on the 8315 RDB runs slower than on some other 83xx
platforms, we can dial down these values without a problem,
thereby decreasing the latency of memory a little.

Since we've changed the memory map of the board, be nice and
add some checking to try to catch out-of-date .dts files. We do
this by checking the CCSRBAR location in the .dts and comparing
it to the CCSRBAR location in u-boot. If they don't match, a
warning msg is printed. This isn't foolproof, but it's simple and
will catch most of the cases where an out-of-date .dts is present,
including all of the cases where a new u-boot is used with an old
standard MPC8641 .dts file as supplied with Linux.

This patch creates a memory map with all the devices
in 36-bit physical space, in addition to the 32-bit map.
The CCSR relocation is moved (again, sorry) to
allow for the physical address to be 36 bits - this
requires translation to be enabled. With 36-bit physical
addressing enabled, we are no longer running with VA=PA
translations. This means we have to distinguish between
the two in the config file. The existing region name is
used to indicate the virtual address, and a _PHYS variety
is created to represent the physical address.
Large physical addressing is not enabled by default.
Set CONFIG_PHYS_64BIT in the config file to turn this on.

The memory map on the 8641hpcn is modified to look more like
the 85xx boards; this is a step towards a more standardized
layout going forward. As part of this change, we now relocate
the flash.
The regions for some of the mappings were far larger than they
needed to be. I have reduced the mappings to match the
actual sizes supported by the hardware.
In addition I have removed the comments at the head
of the BAT blocks in the config file, rather than updating
them. These get horribly out of date, and it's a simple
matter to look at the defines to see what they are set to
since everything is right here in the same file.
Documentation has been changed to reflect the new map, as this
change is user visible, and affects the OS which runs post-uboot.

We define CONFIG_MONITOR_BASE_EARLY to define the initial location
of the bootpage in flash. Use this to create an early mapping
definition for the FLASH, and change the early_bats code to use this.
This change facilitates the relocation of the flash since the early
mappings are no longer tied to the final location of the flash.

There's a lot of setup and foo for the second flash

There are several items in the config file that were hardcoded
but that should really be based on other config options, since
the regions are contiguous and depend on being so. This cleans
that up a bit. Also, add BR_PHYS_ADDR() macro to convert
addresses into the proper format for BR registers.

Currently, the CCSR gets relocated while translation is
enabled, meaning we need 2 BAT translations to get to both the
old location and the new location. Also, the DEFAULT
CCSR location has a dependency on the BAT that maps the
FLASH region. Moving the relocation removes this unnecessary
dependency. This makes it easier and more intutive to
modify the board's memory map.
Swap BATs 3 and 4 on 8610 so that all 86xx boards use the same
BAT for CCSR space.

You can't actually have both, and with some coming changes to
