From 3c7f255039a2ad6ee1e3890505caf0d029b22e29 Mon Sep 17 00:00:00 2001 From: Mark Salter Date: Tue, 15 Apr 2014 22:47:52 -0400 Subject: arm64: efi: add EFI stub This patch adds PE/COFF header fields to the start of the kernel Image so that it appears as an EFI application to UEFI firmware. An EFI stub is included to allow direct booting of the kernel Image.
