This is make naming consistent with the kernel and devicetree and in
preparation of pulling out the common tegra20 code.

Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.
This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

Power supplies must be adjusted in line with clock frequency. This code
provides a simple routine to set the voltage to allow operation at maximum
frequency.

Add support for setting up the memory controller parameters. Boards
can set up an appropriate table in the device tree.

This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.
Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:
aliases {
/* This defines the order of our USB ports */
usb0 = "/usb@0xc5008000";
usb1 = "/usb@0xc5000000";
};

funcmux permits selection of config options for particular peripherals,
such as the pins that are used for that peripheral, if there are several
options.
Add UART selection to start with.

The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.
This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.
Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

Seems people fixed their files to use libfoo.o, but didn't actually
update the creation targets to use $(cmd_link_o_target). Update the
rest of the Makefile's found with grep.

This adds an enum for each pin and some functions for changing the pin
muxing setup.

This adds functions to enable/disable clocks and reset to on-chip peripherals.
