669df7e42d pxe: add support for parsing local syslinux files
Add a new command "sysboot" which parses syslinux menu files and boots
using kernel and initrd specified by menu files. The operation is similar
to "pxe boot" except local files on ext2 or fat filesystem are parsed.

34bd23e42f pxe: parse initrd file from append string
For syslinux, the initrd can be set in the append string as
"initrd=<file>", so try to find it there if we haven't already set the
initrd.

90ba7d7c44 pxe: support absolute paths
If the file path starts with a '/', then don't pre-pend the bootfile path.
This fixes a problem with running 'pxe boot' multiple times where the
bootfile path gets pre-pended to itself each time.

beb9f6c678 pxe: support linux entries for labels
Kernels can be specified using "linux" or "kernel" entry. The difference
is kernel is supposed to detect the type of file, but for u-boot both are
treated the same.

Without this patch, some versions of gcc (at least ELDK 4.2) complain
about dereferencing type-punned pointers.

4c12eeb8b5 Convert cmd_usage() calls in common to use a return value
Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

This is a more sensible name, so rename it.

If no default label is specified, but a situation arises where the
default label should be used, treat the first label specified as the
default label.

06283a6401 Add pxe command
Add pxe command, which is intended to mimic PXELINUX functionality.
'pxe get' uses tftp to retrieve a file based on UUID, MAC address or IP
address. 'pxe boot' interprets the contents of PXELINUX config like file
to boot using a specific initrd, kernel and kernel command line.

This patch also adds a README.pxe file - see it for more details on the
pxe command.
