The current NAND Bootloader setup forces the environment
variables to be in line with the bootloader. This change
enables the configuration to be made in the board include
file instead so that it can be individually enabled.

Two fixes for the nand_wait() function in
drivers/nand/nand_base.c:
1. Use correct timeouts. The original timeouts in Linux
source are 400ms and 20ms not 40s and 20s
2. Return correct error value in case of timeout. 0 is
interpreted as OK.

This patch allows an arch/ppc kernel to be booted by just passing 1 or 2
arguments to bootm. It removes the getenv("disable_of") test that used
to be used for this purpose.

Update the 83xx tree to use I2C support in drivers/fsl_i2c.c. Delete
cpu/mpc83xx/i2c.c, include/asm-ppc/i2c.h, and all references to those files.
Added multiple I2C bus support to fsl_i2c.c.

Replace all instances of CFG_IMMRBAR with CFG_IMMR, so that the 83xx
tree matches the other 8xxx trees.

The 834x rev1.x silicon has one CPU5 errata.
The issue is when the data cache locked with
HID0[DLOCK], the dcbz instruction looks like no-op inst.
The right behavior of the data cache is when the data cache
Locked with HID0[DLOCK], the dcbz instruction allocates
new tags in cache.
The 834x rev3.0 and later and 8360 have not this bug inside.
So, when 834x rev3.0/8360 are working with ECC, the dcbz
instruction will corrupt the stack in cache, the processor will
checkstop reset.
However, the 834x rev1.x can work with ECC with these code,
because the sillicon has this cache bug. The dcbz will not
corrupt the stack in cache.
Really, it is the fault code running on fault sillicon.
This patch fix the incorrect dcbz operation. Instead of
CPU FP writing to initialise the ECC.
CHANGELOG:
* Fix the incorrect dcbz operation instead of CPU FP
writing to initialise the ECC memory. Otherwise, it
will corrupt the stack in cache, The processor will checkstop
reset.

add ft_pci_setup, OF_CPU, OF_SOC, OF_TBCLK, and
STDOUT_PATH configuration bits to mpc8349emds,
mpc8349itx, and mpc8360emds board code.
redo environment to use bootm with the fdtaddr
for booting ARCH=powerpc kernels by default,
and provide default fdtaddr values.
PREREQUISITE PATCHES:
* This patch can only be applied after the following patches have been applied:
1) DNX#2006092142000015 "Add support for the MPC8349E-mITX 1/2"
2) DNX#2006092142000024 "Add support for the MPC8349E-mITX 2/2"
CHANGELOG:
* For the 8349E-mITX, fix some size values in pci_init_board(), enable
the clock for the 2nd USB board (Linux kernel will hang otherwise),
and fix the CONFIG_BOOTARGS macro.
