Driver for the Atmel MACB on-chip ethernet controller.
This driver has been tested on the ATSTK1000 board with a AT32AP7000
CPU. It should probably work on AT91SAM926x as well with some minor
modifications.
Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from

Implement functions for configuring the macb0 and macb1 pins, as
well as functions for getting the clock rate of the various
busses the macb ethernet controllers are connected to.

Instead of creating yet another set of MII register definitions
in the macb driver, here's a complete set of definitions for everyone
to use.

Include the imi, imls and jffs commands sets by default on ATSTK1000.
Also define CONFIG_BOOTARGS to something more useful, define
CONFIG_BOOTCOMMAND and enable autoboot by default.

Conform to the "standard" interface and use initdram() instead of
board_init_memories() on AVR32. This enables us to get rid of the
sdram_size member of the global_data struct as well.

Relocate the u-boot image into SDRAM like everyone else does. This
means that we can handle much larger .data and .bss than we used to.

Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.
As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.

Convert spaces to tabs (must have missed this one last time around),
sort the entries by address and group them together by bus
connectivity.

Add -fPIC -mno-init-got to the avr32-specific CFLAGS to make u-boot
position independent. This will make relocation a lot easier.
-mno-init-got means that gcc shouldn't emit code to load the GOT
address into r6 in every function prologue. We do it once and for
all in the early startup assembly code, so enabling this option
makes u-boot a bit faster and smaller.
The assembly parts have always been position-independent, so no code
changes should be necessary.

It doesn't really matter which toolchain you use to compile u-boot,
but the avr32-linux one is probably what most people have installed.

Split the avr32 initialization code into a function to run before
relocation, board_init_f and a function to run after relocation,
board_init_r. For now, board_init_f simply calls board_init_r
at the end.

The fdt command uses David Gibson's libfdt library to manipulate as well
as print the flattened device tree. This patch is the new command,
the second part is the modifications to the existing code.
Enhanced the formerly private function _fdt_next_tag() to allow stepping
through the tree, used to produce a human-readable dump, and made
it part of the published interface.
Also added some comments.
The board specific "bootstrap" command is now fixed and can
be used for the AMCC Katmai board to configure different
CPU/PLB/OPB frequencies.

Fix a bug in the auto calibration routine. This driver now runs
more reliable with the tested modules. It's also tested with
167MHz PLB frequency (667MHz DDR2 frequency) on the Katmai.

The "old" i2c commands (iprobe, imd...) are now compiled in again,
even when the i2c command tree is enabled via the CONFIG_I2C_CMD_TREE
config option.

This patch adds some 4xx GPIO functions. It also moves some of the
common code and defines into a common 4xx GPIO header file.

Without this patch, I am unable to get to the prompt on rev 2 silicon.
Only set ddrioovcr for rev1.
