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add some checking to try to catch out-of-date .dts files.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will catch most of the cases where an out-of-date .dts is present,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  These get horribly out of date, and it's a simple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.

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
change the memory map for the board and support 36-bit physical,
we need the extra BAT that is being consumed by having both.

I also make non-PCI configs build cleanly, for the sake of sanity.
