This patch series adds PXE booting support to U-boot. It adds aseries of DHCP options to allow U-boot DHCP requests to be compliant with RFC 4578, and a set of commands to provide PXELINUX like behavior.
The pxe 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.
As an example, support for the pxe commands is enabled for the ca9x4_ct_vxp config.
Additional details for the pxe commands are available in the README.pxe file added as part of this patch series.
This patch series adds support for RFC 4578 compliant DHCP request options, which enhance the ability of DHCP servers to respond differently to different clients.
As an example, the last patch in this series enables support for the PXE DHCP options for the ca9x4_ct_vxp config.
v5 of the patch series responds to a couple of comments from Mike Frysinger, and fixes a checkpatch simple_strtoul warning. Details are in the individual patch logs.
