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.

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 These get horribly out of date, and it's a simple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.

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.

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.

The patch is following the commit 3924384060
mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.
lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

The 8572 DDR erratum1:
DDR controller may enter an illegal state when operating
in 32-bit bus mode with 4-beat bursts.
Description:
When operating with a 32-bit bus, it is recommended that
DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used.
This forces the DDR controller to use 4-beat bursts when
communicating to the DRAMs. However, an issue exists that
could lead to data corruption when the DDR controller is
in 32-bit bus mode while using 4-beat bursts.
Projected Impact:
If the DDR controller is operating in 32-bit bus mode with
4-beat bursts, then the controller may enter into a bad state.
All subsequent reads from memory is corrupted.
Four-beat bursts with a 32-bit bus only is used with DDR2 memories.
Therefore, this erratum does not affect DDR3 mode.
Work Arounds:
To work around this issue, software must set DEBUG_1[31] in
DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1
and CCSRBAR offset + 0x6f00 for DDR_2).
Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2
as condition, but it should be DDR_SDRAM_CFG register.
