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.

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.

Whistler is a highly configurable Tegra evaluation and development board.
This change adds support for the following specific configuration:

E1120 motherboard
E1108 CPU board
E1116 PMU board

The motherboard configuration switches are set as follows:
SW1=0 SW2=0 SW3=5
S1/S2/S3/S4 all on, except S3 7/8 are off.

Other combinations of daugher boards may work to varying degrees, but will
likely require some SW adjustment.

Use the POSIX variant of basename due to BSD systems (e.g. OS X) do not provide
GNU version of basename(3). It is save to use the POSIX variant here cause we do
never use argv[0] later on which may be modified by the basename(3) POSIX
variant.
On systems providing GNU variant the GNU variant should be used since string.h
is included before libgen.h. Therefore let the _GNU_SOURCE as is.

This patch fixes following warning (on OS X):
---8<---
mkenvimage.c: In function ‘main’:
mkenvimage.c:105: warning: implicit declaration of function ‘basename’

This patch dramatically drops the amount of time u-boot needs to read a
file from an ext2 partition.  On a typical 2 to 5 MB file (kernels and
initrds) it goes from tens of seconds to a couple seconds.

All we are doing here is grouping contiguous blocks into one read.

Boot tested on Globalscale Technologies Dreamplug (Kirkwood ARM SoC)
with three different files.  sha1sums were calculated in Linux
userspace, and then confirmed after ext2load.

Make the menu timeout apply only when prompt flag is set and after the
menu is displayed. This allows auto boot to work no matter whether prompt
is set or cleared. Use the default selection if the menu times out.

This also fixes the timeout value given to readline_into_buffer to be
seconds instead of 10th of seconds.

Old behavior:

if prompt
  display menu and wait for choice
else
  wait for timeout
  if key pressed
    display menu and wait for choice
  else
    exit command

New behavior:

if prompt
  display menu
  if key pressed
    wait for choice
  else
    boot default entry on timeout

Add support for a second flash.
By default, a single flash chip is set up:
- called 'boot'
- mtd name for ubi 'ubi0'
MTDIDS and MTDPARTS may be overwritten to add a second flash.
The 'ubiattach' command is featured in two versions:
- if CONFIG_KM_UBI_PARTITION_NAME_APP is not defined:
  this is the version as up to now
- if CONFIG_KM_UBI_PARTITION_NAME_APP is defined:
  a check on 'actual_bank' will be done to determine the flash to boot
  from.

Use CONFIG_KM_UBI_PARTITION_NAME_BOOT and
CONFIG_KM_UBI_PARTITION_NAME_APP to define where to put the bootloader
and the applications.

Example:
In the board config do:
... snip ...

       "boot:"                                                 \
               "768k(u-boot),"                                 \
               "128k(env),"                                    \
               "128k(envred),"                                 \
               "-(" CONFIG_KM_UBI_PARTITION_NAME_BOOT ");"     \
       "app:"                                                  \
               "-(" CONFIG_KM_UBI_PARTITION_NAME_APP ");"

... snap ...
