From f82a7840f11d008f06b8c8d5578d2f4b8eeaa285 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 27 Apr 2015 14:16:02 +0800 Subject: x86: quark: Turn on legacy segments decode By default the legacy segments (A0000h-B0000h, E0000h-F0000h) do not decode to system RAM. Turn on the decode so that we can write configuration tables in the F segment.
