7651f8bdbb Fix serious pointer bug with bootm and reserve map.
What was suppose to be a stack variable was declared as a pointer,
  overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile.  That is
  The U-Boot Way.

64dbbd40c5 Moved fdt command support code to fdt_support.c
...in preparation for improving the bootm command's handling of fdt blobs.
Also cleaned up some coding sloppiness.

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.

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.
