be5e61815d mpc83xx: Update 83xx to use fsl_i2c.c
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.

d239d74b1c mpc83xx: Replace CFG_IMMRBAR with CFG_IMMR
Replace all instances of CFG_IMMRBAR with CFG_IMMR, so that the 83xx
tree matches the other 8xxx trees.

90f30a710a mpc83xx: Fix the incorrect dcbz operation
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.

bf0b542d67 mpc83xx: add OF_FLAT_TREE bits to 83xx boards
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.
