6d0363b23a amcc-common.h: Use filenames from environment variables for update procedure.
Using a separate "u-boot" environment variable allows to easily
specify different filenames for the update procedure.  This is also in
line with many other board configurations defining an "update" script.

bbff2d2861 ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.  By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.

5079ae4a20 ppc/85xx: Clean up do_reset
There is no reason to do a run time check for e500 v1 based cores to
determine if we have the GUTs RSTCR facility.  Only the first generation
of PQ3 parts (MPC8540/41/55/60) do not have it.  So checking to see if
we are e500 v2 would miss future parts (like e500mc).

Just change this to be ifdef'd based on CONFIG_MPC85{40,41,55,60}.

ef4025cf61 ppc/85xx/86xx: Device tree fixup for number of cores
Fixing the number of cores in the device tree based on the actual number of
cores on the system.  With this same device tree image can be used for dual
core and single core members of otherwise exactly same SOC.

For example:
* P2020RDB and P2010RDB
* P1020RDB and P1011RDB
* MPC8641D and MPC8641

eb0a2cc9e3 ppc/85xx: Fix bug in setup_mp code
Its possible that we try and copy the boot page code out of flash into a
DDR location that doesn't have a TLB cover it.  For example, if we have
3G of DDR we typically only map the first 2G.  In the cases of 4G+ this
wasn't an issue since the reset page TLB mapping covered the last page
of memory which we wanted to copy to.

We now change the physical address of the reset page TLB to map to the
true physical location of the boot page code, copy and than set the
TLB back to its 1:1 mapping of the reset page.

e568fd99ab 85xx: Add support for setting IVORs to fixed offset defaults
In future Book-E implementations IVORs will most likely go away and be
replaced with fixed offsets.  The IVPR will continue to exist to allow
for relocation of the interrupt vectors.

This code adds support to setup the IVORs as their fixed offset values

either via 'bootm' or a cpu release.

14bdd93270 fsl_i2c: increase I2C timeout values and make them configurable
The value of I2C_TIMEOUT in fsl_i2c.c has several problems.  First, it is
defined as CONFIG_HZ/4, but it is used as a count of microseconds, so it makes
no sense to derive it from a clock rate.  Second, the current value (250) is
too low for some boards, so it needs to be increased.  Third, the timeout
necessary for multiple-master arbitration is larger than the timeout for basic
read/write operations, so we shouldn't have a single constant for both timeouts.
Finally, it would be nice if we could override these values on a per-board
basis.

9179dd3bf5 Reset i2c slave devices during init on mpc5xxx cpus
Reset any i2c devices that may have been interrupted during a system reset.
Normally this would be accomplished by clocking the line until SCL and SDA
are released and then sending a start condtiion (From an Atmel datasheet).
There is no direct access to the i2c pins so instead create start commands
through the i2c interface.  Send a start command then delay for the SDA Hold
time, repeat this by disabling/enabling the bus a total of 9 times.

up with the normal binary size.  The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode.  This standalone
