[Xen-devel] [PATCH OSSTEST v4 08/21] ts-host-install: Support UEFI PXE boot using grub.efi

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Handling of chainloading from the local hdd in
setup_pxeboot_local_uefi will be added in the next patch.

(Wrap DiBase entry in README too for consistency)

v4: Turn grub "echo todo" into a die.
v3: Reindent README (fix DiBase too for consistency)

      {firmware} at end
    Rewrap setup_grub_efi_bootcfg
    Adjust for setup_pxeboot -> setup_pxeboot_di
