A known hardware issue of USB1 port where bit 1 (connect status
change) of PORTSC register will be set after issuing Port Reset
(like "usb reset" in u-boot command line).
This will be treated as an error and stops later device enumeration.
Therefore we clear that bit after Port Reset in order to proceed
later device enumeration.

Walk the BIT and BCT to find the ODMDATA word in the
CustomerData field and put it into Scratch20 reg for
use by kernel, etc.
Built all Tegra builds OK; Booted on Seaboard and saw
ODMDATA in PMC scratch20 was the same as the value in my
burn-u-boot.sh file (0x300D8011). NOTE: All flash utilities
will have to specify the odmdata (nvflash --odmdata n) on
the command line or via a cfg file, or built in to their
BCT.

We want to know which type of chip we are running on - the Tegra
family has several SKUs. This can be determined by reading a
fuse register, so add this function to ap20.

These headers provide access to additional Tegra features.
flow - start/stop CPUs
sdram - parameters for SDRAM
fuse - access to on-chip fuses / security settings
gp_padctl - pad control and general purpose registers

Change this name to fit with the current convention in the Tegra
header file.

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";
};

This driver supports SPI on Tegra2, running at 48MHz.
