From 83d9712e70dcd704462a3dc53254a05087c231f0 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 5 Mar 2015 11:21:03 +0800 Subject: x86: Add queensbay fsp patch information in README.x86 The FSP release version 001 for Intel Queensbay has a bug which could cause random endless loop during the FspInit call. This bug was published by Intel although Intel did not describe any details. Describe this information in the x86 doc so that U-Boot Queensbay support is invulnerable.
