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.

Expanded OCM TLB to allow access to 64K OCM as well as 256K of
internal SRAM.
Adjusted internal SRAM initialization to match updated user
manual recommendation.
OCM & ISRAM are now mapped as follows:
physical virtual size
ISRAM 0x4_0000_0000 0xE300_0000 256k
OCM 0x4_0004_0000 0xE304_0000 64k
A single TLB was used for this mapping.

Added include/asm-ppc/ppc4xx-isram.h and moved internal SRAM and
L2 cache DCRs from ppc440.h to this new header.
Also converted these DCR defines from lowercase to uppercase and
modified referencing modules to use them.

The definitions of bits in SDR_CFG are incorrect, and not used within
U-Boot. Therefore, they can be removed.
The naming of the sdr_ddrdl/sdr_cfg registers do not follow conventions,
and are unused, so they can be removed too.
A definition for SDR0_DDRCFG is added.

Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

Doing trap_init immediately once we're running from RAM
means we're no longer dependent on the physical location of
the flash on non-BookE platforms. Before trap_init, those
platforms switch to real mode and go to 0xfff00100 on exception.
After the switch, they go to 0x00000100 This makes it easier to
move the flash location.

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.

Using a mtmsr/blr means that you have to be executing at the
same virtual address once you enable translation. This is
unnecessarily restrictive, and is not really how this is
usually done. Change it to use the more common mtspr SRR0/SRR1
and rfi method.

There's a lot of setup and foo for the second flash
bank. The problem is, this board doesn't actually have one.
Clean this up. Also, the flash is 8M in size. Get rid
of the confusing aliased overmapping, and just map 8M.

In order to later allow for a physical relocation of the
flash, setup_bats, which sets up the final BAT mapping
for the board, needs to happen *after* init_laws().
Otherwise, there will be no window programmed for the flash
at the new physical location at the point when we change
the mmu translation.

This patch provides support for AFEB9260 board, a product of
OpenSource hardware and software. Some commertial projects
are made with this design. A board is basically AT91SAM9260-EK
with some modifications and different peripherals and different
parts used. Main purpose of this project is to gain experience in
hardware design.
