Bug#873390: [PATCH] flash-kernel: Provide hook to start EFI application

Package: flash-kernel
Version: 3.84
Severity: wishlist

Instead of starting the Linux kernel from U-Boot we may want to
start an EFI application like grub or iPXE. Let us use a new
hook @@UBOOT_PREBOOT_EXTRA@@ in the boot.scr generation for this
purpose. The related hook files are to be placed in
/etc/flash-kernel/preboot.d or /usr/share/flash-kernel/preboot.d.
