00a2749d7b tegra20: rename tegra2 -> tegra20
This is make naming consistent with the kernel and devicetree and in
preparation of pulling out the common tegra20 code.

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.

f9f2f12e2c tegra: seaboard: disable SPI, move environment to eMMC
The SPI hardware on Seaboard is too broken to use; it is muxed with the
console UART and requires evil interactions between the SPI and UART
drivers to work even partially. The current code in U-Boot is not
sufficient to make this work correctly; auto boot is aborted due to
corruption in the UART RX channel interrupting it.

Instead, move the environment to eMMC, at the end of the second boot
sector. This should not conflict with any other eMMC usage, irrespective
of whether the board boots from SPI, NAND, or eMMC: if U-Boot is stored
in eMMC, it will be stored well below this location. The kernel only
uses the general area of the eMMC once booted, not the boot sectors.

Boards that are derivatives of Seaboard don't have the muxing issue,
and should/could have a separate U-Boot configuration file that does
enable SPI if desired.

Alternatively, the environment could be stored in NAND flash, but we
currently have no driver for that controller.

59f8ac65f8 tegra: remove CONFIG_USB_ETHER_SMSC95XX from boards without it
The SMSC95xx series may exist either directly on a main board, or as a USB
to Ethernet dongle. However, dongles containing these chips are very rare.
Hence, remove this config option, except on Harmony where such a chip is
actually present on the board.

The asix option remains, since it's a popular chip, and I actively use a
dongle containing this.

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.

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.
