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
|
