Thierry Reding 1cbdf2d7e1 tegra: medcom: Add device tree support
Device tree support is required for working USB host support, which in
turn enables ethernet support.

Tom Warren 76e350b7a3 arm: Tegra: Use ODMDATA from BCT in IRAM
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.

Tom Warren 3f82d89d3d mmc: tegra2: rename tegra2_mmc.* to tegra_mmc.*
In anticipation of Tegra3 support, continue removing/renaming
Tegra2-specific files. No functional changes (yet).
Updated copyrights to 2012.

Stephen Warren bea2674ccd tegra: flesh out bootcmd
This implements a useful bootcmd for Tegra. The boot order is:

* If USB enabled, USB storage
* Internal MMC (SD card or eMMC)
* If networking is enabled, BOOTP/TFTP

When booting from USB or MMC, the boot script is assumed to be in
partition 1 (although this may be overridden via the rootpart variable),
both ext2 and FAT filesystems are supported, the boot script may exist
in either / or /boot, and the boot script may be named boot.scr.uimg or
boot.scr.

When booting over the network, it is assumed that boot.scr.uimg exists
on the TFTP server. There is less flexibility here since those setting
up network booting are expected to need less hand-holding.

In all cases, it is expected that the initial file loaded is a U-Boot
image containing a script that will load the kernel, load any required
initrd, load any required DTB, and finally bootm the kernel.

Stephen Warren 07a84b7b19 tegra: remove some cruft from CONFIG_EXTRA_ENV_SETTINGS
console isn't used by anything, and the kernel should be set appropriately
by whatever script is booting the kernel, not imposed by the bootloader.

mem might be useful, but the current value is pretty bogus, since it
includes nvmem options that make no sense for an upstream kernel, and
equally should not be required for any downstream kernel. Either way, this
is also best left to the kernel boot script.

smpflag isn't used by anything, and again was probably intended to be a
kernel command-line option better set by the kernel boot script.

Thierry Reding c91915e905 tegra2: Add Avionic Design Medcom support.
The Medcom is a 16:9 15" terminal that is used for patient infotainment
in hospitals.

Changes in v3:
  * Remove unused implementation of gpio_config_uart().
  * Implement MMC/SD card detection.
  * Drop board_mmc_getcd() which is now implemented by common Tegra2
    code.
  * Add MAINTAINERS entry.

Changes in v2:
  * No longer override the default CONFIG_SYS_TEXT_BASE setting.
