From 4e4479a8922833025a8aac4f33fff9fa1e294ac9 Mon Sep 17 00:00:00 2001 From: Albert Aribaud <[albert.aribaud@free.fr]> Date: Thu, 26 Aug 2010 14:05:19 +0530 Subject: [PATCH] Orion5x: bugfix: window size (mis)calculation Fix orion5x_winctrl_calcsize() off-by-1 bug which caused mapping windows to be cut by half. This afected all windows including NOR flash (causing half the flash to be unaccessible) but DRAM was and still is fine as its size is determined otherwise.
