c78c678354 mpc83xx: MPC837XEMDS: Fixup eSDHC nodes in device tree
fdt_fixup_esdhc() will either disable or enable eSDHC nodes, and
also will fixup clock-frequency property.

Plus, since DR USB and eSDHC are mutually exclusive, we should
only configure the eSDHC if asked through hwconfig.

environment.  So, let's make sure the define is named accordingly.

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.

8b34557c54 mpc83xx: Add PCI-E support for MPC837XEMDS boards
MPC837XEMDS boards can support PCI-E via "PCI-E riser card". The card
provides two PCI-E (x2) ports. Though, only one port can be used in x2
mode. Two ports can function simultaneously in x1 mode.

PCI-E x1/x2 modes can be switched via "pex_x2" environment variable.

b3379f3fd1 mpc83xx: add ELBC NAND support for the MPC837XEMDS boards
Though NAND chip is replaceable on the MPC837XE-MDS boards, the
current settings don't work with the default chip on the board.
Nevertheless Freescale's U-Boot sets the option register correctly,
so I just dumped the register from the working u-boot. My guess is
that the old settings were applicable for some pilot boards, not
found in the production.

This patch also enables FSL ELBC driver so that we could access
the NAND storage in the u-boot.

The NAND support costs about 45KB, so the u-boot no longer fits
into two 128KB NOR flash sectors, thus we also have to adjust
environment location: add another 128KB to the monitor length.

Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

It is due to hardware design and logic defect, that is the
I/O[0:7] of NAND chip is connected to LAD[7:0], so when
the NAND chip connected to nLCS3,  you have to set up the
OR3[BCTLD] = '1' for normal operation, otherwise it will have
bus contention due to the pin 48/25 of U60 is enabled.

Setup the OR3[BCTLD] = '1' , that meaning the LBCTL is not
asserted upon access to the NAND chip, keep the default state.

00f7bbae92 mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards
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.
