From 1dcf83fd0c42525dd36cfeb61fe0bfb12113c6b3 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 29 Apr 2008 14:20:23 +0100 Subject: toshiba: use ioremap_cached The switch of ioremap to default to uncached doesn't break this driver but it does needlessly slow it down as BIOS space is cachable and this driver is quite happy scanning cached ROM space.
