d873133f2b ppc4xx: Add Sequoia RAM-booting target
This patch adds another build target for the AMCC Sequoia PPC440EPx
eval board. This RAM-booting version is targeted for boards without
NOR FLASH (NAND booting) which need a possibility to initially
program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000)
configured to setup the SDRAM, this debugger can load this RAM-
booting image to the target address in SDRAM (in this case 0x1000000)
and start it there. Then U-Boot's standard NAND commands can be
used to program the NAND FLASH (e.g. "nand write ...").

Here the commands to load and start this image from the BDI2000:

440EPX>reset halt
440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin
440EPX>go 0x1000000

Please note that this image automatically scans for an already
initialized SDRAM TLB (detected by EPN=0). This TLB will not be
cleared. This TLB doesn't need to be TLB #0, this RAM-booting
version will detect it and preserve it. So booting via BDI2000
will work and booting with a complete different TLB init via
U-Boot works as well.

9a929170be ppc4xx: Disable POST memory test on NAND-booting Sequoia
Don't run the memory POST on the NAND-booting version. It will
overwrite part of the U-Boot image which is already loaded from NAND
to SDRAM. We were just lucky that it booted at all with this SDRAM
test enabled.

6c869637fe NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS
This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define

 #define NAND_MAX_CHIPS          CONFIG_SYS_MAX_NAND_DEVICE

but that's bogus and did not work anyhow.

72675dc6c0 ppc4xx: Unify AMCC's board config files (part 3/3)
This patch series unifies the AMCC eval board ports by introducing
a common include header for all AMCC eval boards:

include/configs/amcc-common.h

This header now includes all common configuration options/defines which
are removed from the board specific headers.

The reason for this is ease of maintenance and unified look and feel
of all AMCC boards.

14f73ca679 ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"
If CFG_MEM_TOP_HIDE is defined in the board config header, this specified
memory area will get subtracted from the top (end) of ram and won't get
"touched" at all by U-Boot. By fixing up gd->ram_size the Linux kernel
should gets passed the now "corrected" memory size and won't touch it
either. This should work for arch/ppc and arch/powerpc. Only Linux board
ports in arch/powerpc with bootwrapper support, which recalculate the
memory size from the SDRAM controller setup, will have to get fixed
in Linux additionally.

This patch enables this config option on some PPC440EPx boards as a workaround
for the CHIP 11 errata. Here the description from the AMCC documentation:

CHIP_11: End of memory range area restricted access.
Category: 3

Overview:
The 440EPx DDR controller does not acknowledge any
transaction which is determined to be crossing over the
end-of-memory-range boundary, even if the starting address is
within valid memory space. Any such transaction from any PLB4
master will result in a PLB time-out on PLB4 bus.

Impact:
In case of such misaligned bursts, PLB4 masters will not
retrieve any data at all, just the available data up to the
end of memory, especially the 440 CPU. For example, if a CPU
instruction required an operand located in memory within the
last 7 words of memory, the DCU master would burst read 8
words to update the data cache and cross over the
end-of-memory-range boundary. Such a DCU read would not be
answered by the DDR controller, resulting in a PLB4 time-out
and ultimately in a Machine Check interrupt. The data would
be inaccessible to the CPU.

Workaround:
Forbid any application to access the last 256 bytes of DDR
memory. For example, make your operating system believe that
the last 256 bytes of DDR memory are absent. AMCC has a patch
that does this, available for Linux.

This patch sets CFG_MEM_TOP_HIDE for the following 440EPx boards:
lwmon5, korat, sequoia

The other remaining 440EPx board were intentionally not included
since it is not clear to me, if they use the end of ram for some
other purpose. This is unclear, since these boards have CONFIG_PRAM
defined and even comments like this:

PMC440.h:
/* esd expects pram at end of physical memory.
 * So no logbuffer at the moment.
 */

It is strongly recommended to not use the last 256 bytes on those
boards too. Patches from the board maintainers are welcome.

81b73dec16 ppc4xx: (Re-)Enable CONFIG_PCI_PNP on AMCC 440EPx Sequoia
The 440EPx has a problem when the PCI_CACHE_LINE_SIZE register is
set to non-zero, because it doesn't support MRM (memory-read-

o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow
  board-specific settings. As an example the sequoia board requires 0.

o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the
  PCI IO-space. Obtained from Stefan Roese <sr@denx.de>.
