From 8e515d36b467a1457bab8947ccf4ddf61a85ac8f Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Sat, 23 Jun 2012 15:43:41 -0700 Subject: RTC: Enable extended CMOS in the bootblock This makes it available early in romstage without having to worry when the different romstagse enable it. Check for extended CMOS to be enabled in early romstage. This is used by a later commit which uses the extended CMOS region for stoage.
