OpenWrt UEFI Support (19.07 Branch, Unofficial Support)
IMPORTANT
Openwrt has officially supported UEFI, but v19.07 and v18.06 not. So v19.07 and v18.06 will continue to update.
Since OpenWrt Project has not yet accepted any UEFI-Boot approach, extract based on the original jow.git and modify it to be compatible with the current version.
These patches are for the convenience of quickly adding UEFI startup support and these are temporary solutions.
Tested in Openwrt 19.07.8
