Now that warm booting is not supported, there isn't a need for the
BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them.
Note that this change makes the board info bd_bootflags field useless.
It will always be set to 0, but we leave it around so that we don't
break the board info structure that some OSes are expecting to be passed
from U-Boot.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Newer Linux kernels can overrun the initial memory window used for
booting with their BSS area. When this happens, they overwrite the FDT
and silently fail to boot.
On e300 CPUs, the Linux kernel uses an initial BAT covering the first
256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
allowed by Linux. This will allow very large kernels to boot.

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.

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.

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.
