Add UEFI support for iPXE
This patch adds UEFI support for iPXE, the changes made are: * Remove conditional preventing iPXE to be configured with UEFI * Add the boot_mode= kernel parameter to the iPXE template * Add initrd=deploy_ramdisk kernel parameter to the iPXE template. The UEFI support in iPXE requires the kernel argument to match what the initrd expects. For more information see [0] [0] http://forum.ipxe.org/showthread.php?tid=7589&pid=11843#pid11843 Closes-Bug: #1525989 Change-Id: I6e74bc6332c5aba92ef0de8694fd4259c596cf03
