Subject: [PATCH 10/36] add header with a generic set of boot commands defined.
As the next step in a generic config we are introducing a set of generic boot
paramaters. Depending on the hardwares configuration, booting from supported
hardware will be enabled, mmc, usb, sata, scsi, ide, pxe and dhcp.
There is nothing to stop this being extended to support nand and any other
type of storage that comes along. An ideal future enhancement will be to
allow the user to dynamically reorder the boot devices, and allow one off
boots. for example simply be able to pxe boot to reinstall
