some LCRR bits are not documented throughout the 83xx family RMs.
New board porters copying similar board configurations might omit
setting e.g., DBYP since it was not documented in their SoC's RM.
Prevent them bricking their board by retaining power on reset values
in bit fields that the board porter doesn't explicitly configure
via CONFIG_SYS_<registername>_<bitfield> assignments in the board
config file.
also move LCRR assignment to cpu_init_r[am] to help ensure no
transactions are being executed via the local bus while CLKDIV is being
modified.
also start to use i/o accessors.

when using Linus' 83xx_defconfig, the mpc8377rdb would hang at boot
at either:
NET: Registered protocol family 16
or the
io scheduler cfq registered
message. Fixing up these DDR settings appears to fix the problem.

This patch adds support for eSDHC on MPC837XERDB boards. The WP
switch doesn't seem to work on RDB boards though, the WP pin is
always asserted (can see the pin state when it's in GPIO mode).
FSL DR USB and FSL eSDHC are mutually exclusive because of pins
multiplexing, so user should specify 'esdhc' or 'dr_usb' options
in the hwconfig environment variable to choose between the
devices.
p.s.
Now we're very close to a monitor len limit (196 bytes left using
gcc-4.2.0), so also increase the monitor len by one sector (64 KB).

Saving the environment leads to overwriting u-boot itself,
bricking boards. Increase u-boot's image size so the environment
base address doesn't end up overlapping u-boot text.

bootdelay set to -1 'permanently' disables autobooting, even if

Change all code that conditionally operates on high bat
registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS
instead of the myriad ways this is done now. Define the option
for every config for which high bats are supported (and

enabled)

Currently the SATA controller clock is configured as CSB clock,
usually the CSB clock is 400/333/266MHz.
However, The SATA IP block is only guaranteed to operate up to
200 MHz as stated in the HW spec.
The bug is reported by Joe D'Abbraccio <ljd015@freescale.com>
This patch makes the SATA clock as half of CSB clock.
