The ecm variable in sdram.c was being declared for all 8548, but only
used by specific 8548 boards, so we make that variable require those
specific boards, too
The nand code was using an index "i" into a table, and then re-using "i"
to set addresses for each upm. However, then it relied on the old value
of i still being there to enable things. Changed the second "i" to "j"

This patch adds the workaround for erratum DDR20 according to MPC8548
Device Errata document, Rev. 1: "CKE signal may not function correctly
after assertion of HRESET". Furthermore, the bug DDR19 is fixed in
processor version 2.1 and the work-around must be removed.

This patch makes accesses to the system memory cachable by removing the
caching-inhibited and guarded flags from the relevant TLB entries for
the TQM8548_BE and TQM8548_AG modules. FYI, the Freescale MPC85* boards
are configured similarly.
This results in a big averall performace improvement. TFTP downloads,
NAND Flash accesses, kernel boots, etc. are much faster.

The TQM8548_BE is a variant of the TQM8548 module with NAND and CAN
interface. With NAND support, the image is significantly larger and
TEXT_BASE is adjusted accordingly. U-Boot can be built for this
module with "$ make TQM8548_BE_config".

The TQM8548_AG module does not have the standard PCI/PCI-X interface
connected but just the PCI Express interface . So far it was not
possible to disable it without disabling the complete PCI interface
(CONFIG_PCI) including PCI Express.

As the reset vector is located at 0xfffffffc, all flash sectors from the
beginning of the U-Boot binary to 0xffffffff must be protected. On the
TQM8548-AG having small sectors at the end of the flash it happened that
the last two sector were not protected and an "erase all" left an
un-bootable system behind:
Bank # 2: CFI conformant FLASH (32 x 16) Size: 32 MB in 270 Sectors
AMD Standard command set, Manufacturer ID: 0xEC, Device ID: 0x257E
Erase timeout: 8192 ms, write timeout: 1 ms

The same bug seems to be in drivers/mtd/cfi_flash.c:flash_init() and many
board BSPs as well.

Update the 86xx reset sequence to try executing a board-specific reset
function. If the board-specific reset is not implemented or does not
succeed, then assert #HRESET_REQ. Using #HRESET_REQ is a more standard
reset procedure than the previous method and allows all board
peripherals to be reset if needed.

The device tree's PHY addresses need to be fixed up if we're using the

In the 36-bit physical config for MPC8572DS when need the start address
of memory and it size to be kept in phys_*_t instead of a ulong since
we support >4G of memory in the config and ulong cant represent that.
Otherwise we end up seeing the memory node in the device tree reporting
back we have memory starting @ 0 and of size 0.

When we introduced the 36-bit config of the MPC8572DS board we had the
wrong PCI MEM bus address map. Additionally, the change to the address
map exposes a small issue in our dummy read on the ULI bus. We need
to use the new mapping functions to handle that read properly in the
36-bit config.

The BAT fields are architected; there's no need for these to be in
cpu-specific files. Drop the duplication and move these to
include/asm-ppc/mmu.h. Also, remove the BL_xxx defines that were only
used by the alaska board, and switch to using the BATU_BL_xxx defines
used by all the other boards. The BL_ defines previously in use
had to be shifted into the proper position for use, which was inefficient.

Because the inbound pci windows are mapped generously, set up
the more specific outbound windows first. This way, when we
search the pci regions for something, we will hit on the more
