Enable hush shell, environment in flash rather in EEPROM,
more user-friendly default environment, etc.
The simple EEPROM environment can be selected easily in the board
config file.

G2 core reference manual says decrementer and time base
are decreasing/increasing once every 4 bus clock cycles.
Lets fix it, so time in Linux won't run twice as fast

Now 405EZ ports also show upon bootup from which boot device
they are configured to boot:
U-Boot 1.2.0-gd3832e8f-dirty (Apr 18 2007 - 07:47:05)
CPU: AMCC PowerPC 405EZ Rev. A at 199.999 MHz (PLB=133, OPB=66, EBC=66 MHz)
Bootstrap Option E - Boot ROM Location EBC (32 bits)
16 kB I-Cache 16 kB D-Cache
Board: Acadia - AMCC PPC405EZ Evaluation Board

Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs.
The AT91 ARM-based CPUs use basically the same hardware, so it should
be possible to share this driver, but no effort has been made so far.
Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from
http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

Implement MACB initialization for AVR32 and ATSTK1000, and turn

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.

Changed _fdt_check_header() to fdt_check_header() and made it part of
the interface - it is a useful routine.
Also did some asthetics cleanup to the include files (headers).
With this new base address of the Xilinx SystemACE controller
the Linux driver will be easier to adapt, since it can now be
mapped via the "normal" ioremap() call.

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.
