The clock dividers that were used do not match at all the reference manual. They
were either completely broken, or came from an early silicon revision
incompatible with the current one.

AM/DM37x SoCs add the CTRL_WKUP_CTRL register. It contains the
GPIO_IO_PWRDNZ bit, which is required to be set to enable the I/O pads
of gpio_126, gpio_127 and gpio_129.

The computation was not correct with low clock values: setting a 1MHz
clock would result in an overlap that would then configure a 25Mhz
clock.
This patch implements a correct computation method according to the
kirkwood functionnal spec. table 600 (Serial Memory Interface
Configuration Register).

Define ARCH_MXC for i.MX devices. This is useful to identify features or
behaviors common to all i.MX SoCs.
The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

Allow usage of the imx-common/iomux-v3.h framework by including pad settings
for the i.MX51. The content of the file is taken from Linux kernel at
commit 5d23b39 plus the required changes to make it work in U-Boot.
The contained pad settings are the minimum required to make an Efika MX boot
and get all the currently-implemented peripherals working in U-Boot.
It is recommended that this file not be just a dumping ground for pins but
only contain the settings required for all the boards using it.
Changes for v2:
* reference commit id from Linux kernel
* additionally roll in the USB pads
* removed GPIO_NUMBER define

Add support for tegra20 arm7 boot processor. This processor is used
to power on the Cortex A9 and transfer control to it. In tegra this
processor is an ARM7TDMI not an ARM720T, but since we don't use cache
it was easier to just reuse the ARM720T code as the processors are
otherwise identical except for cache and MMU.

This SoC is used in the Raspberry Pi, for example.
For more details, see:
http://www.broadcom.com/products/BCM2835
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf.
Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.
