From 685224815bee3a79472ab1a8f345c04d7ea2804b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 25 Apr 2015 11:46:43 -0600 Subject: [PATCH] x86: Correct Minnowboard instructions to use the right descriptor The descriptor provided with the FSP does not seem to work. Update the instructions to use the descriptor from the original Intel firmware.
