[U-Boot] [PATCH 0/4] Add support for pxecfg commands

[Jason Hobbs]

The pxecfg commands provide a near subset of the functionality provided
by the PXELINUX boot loader. This allows U-boot based systems to be
controlled remotely using the same PXE based techniques that many non
U-boot based servers use. To avoid identity confusion with PXELINUX, and
because not all behavior is identical, we call this feature 'pxecfg'.

As an example, support for the pxecfg commands is enabled for the
ca9x4_ct_vxp config.

Additional details are available in the README file added as part of
this patch series.
