From f7d7d01be53cb47e0ae212c4e968aa28b82d2138 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Tue, 15 Nov 2011 12:56:14 +0000 Subject: x86: Don't use magic strings for EFI loader signature Introduce a symbol, EFI_LOADER_SIGNATURE instead of using the magic strings, which also helps to reduce the amount of ifdeffery.
