The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB,
standalone or acting as a PCI agent. User's Guide says:

- When the CPLD recognizes its location on the PIB it automatically
  configures RCW to the PCI Host.
- If the CPLD fails to recognize its location then it is automatically
  configured as an Agent and the PCI is configured to an external arbiter.

This sounds good. Though in the standalone setup the CPLD sets PCI_HOST
flag (it's ok, we can't act as PCI agents since we receive CLKIN, not
PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without
any arbiter bad things will happen (here the board hangs during any config
space reads).

In this situation we must disable the PCI. And in case of anybody really
want to use an external arbiter, we provide "pci_external_aribter"
environment variable.

The rfcks should be shifted by 28 bits left. We didn't notice the bug
because we were using only 100MHz clocks (for which rfcks == 0).

Though, for SGMII we'll need 125MHz clocks.

MPC837xE specs says that SerDes1 has:

— Two lanes running x1 SGMII at 1.25 Gbps;
— Two lanes running x1 SATA at 1.5 or 3.0 Gbps.

And for SerDes2:

— Two lanes running x1 PCI Express at 2.5 Gbps;
— One lane running x2 PCI Express at 2.5 Gbps;
— Two lanes running x1 SATA at 1.5 or 3.0 Gbps.

The spec also explicitly states that PEX options are not valid for
the SD1.

Nevertheless MPC8378 RDB and MDS boards configure the SD1 for PEX,
which is wrong to do.

Currently 64M of LBC SDRAM are mapped at 0xF0000000 which makes
it difficult to use (b/c then the memory is discontinuous and
there is quite big memory hole between the DDR/SDRAM regions).

This patch reworks LBC SDRAM setup so that now we dynamically
place the LBC SDRAM near the DDR (or at 0x0 if there isn't any
DDR memory).

With this patch we're able to:

- Boot without external DDR memory;
- Use most "DDR + SDRAM" setups without need to support for
  sparse/discontinuous memory model in the software.

The Arches Evaluation board is based on the AMCC 460GT SoC chip.
This board is a dual processor board with each processor providing
independent resources for Rapid IO, Gigabit Ethernet, and serial
communications. Each 460GT has it's own 512MB DDR2 memory, 32MB NOR
FLASH, UART, EEPROM and temperature sensor, along with a shared debug
port. The two 460GT's will communicate with each other via shared
memory, Gigabit Ethernet and x1 PCI-Express.

Several customers have reported problems with the environment in
EEPROM, including corrupted content after board reset. Probably the
code to prevent I2C Enge Conditions is not working sufficiently.

We move the environment to flash now, which allows to have a backup
copy plus gives much faster boot times.

Also, change the default console initialization to 115200 bps as used
on most other boards.

Not like 8544, 8572 has 4 eTsec so that the other two's pixis bits
are not supported by 8544. Therefor, define PIXIS_VSPEED2_MASK and

Because some dimm parameters like n_ranks needs to be used with the board
frequency to choose the board parameters like clk_adjust etc. in the
