Patch by Haavard Skinnemoen, 06 Sep 2006
This is a first attempt at creating a common serial driver for Atmel
chips. For now, it supports the AT32AP7000 AVR32 chip, but it should
be possible to support AT91RM9200 and other ARM-based chips with some
minor modifications.
There's nothing fundamentally AVR32-specific in this driver, but it
does use some features which are currently only defined for the
AT32AP CPU port:
* pm_get_clock_freq: Obtain the clock frequency of a given domain
* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
For more information about these features, please see the "AT32AP
CPU" patch.
Patch by Haavard Skinnemoen, 06 Sep 2006
This patch adds support for the AT32AP CPU family and the AT32AP7000
chip, which is the first chip implementing the AVR32 architecture.
The AT32AP CPU core is a high-performance implementation featuring a
7-stage pipeline, separate instruction- and data caches, and a MMU.
For more information, please see the "AVR32 AP Technical Reference":
http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf
In addition to this, the AT32AP7000 chip comes with a large set of
integrated peripherals, many of which are shared with the AT91 series
of ARM-based microcontrollers from Atmel. Full data sheet is
available here:

In config.mk, -Wa,-gstabs is unconditionally appended to AFLAGS no
matter what the target's preferred debugging format is. This patch
simply replaces -gstabs with -g, so that the default debugging format
for the architecture is used.
Replace private IMMAP I2C structures with generic reg block
and allow 86xx to have multiple I2C device busses.

Introduced COFIG_FSL_I2C to select the common FSL I2C driver.
And removed hard i2c path from a few u-boot.lds scipts too.
Minor whitespace cleanups along the way.

conditional expressions instead.
Use consistent return code 0/-1 for good/bad indicators.
Include one fewer file if the driver isn't used at all.

When CONFIG_OF_FLAG_TREE is set, the compiler complains that 'len' in
do_bootm_linux() may be uninitialized. There is no possibility in the
current code that len will get used uninitialized, but this fix follows
the existing convention of setting both len and data to zero at the same
time.
