From 4f3cbd79afd99cc5143b2beb126e7425af7f1ff9 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 30 Jan 2014 15:27:26 +0100 Subject: microblaze: Define readq and writeq IO helper function Some drivers check if readq/writeq functions are defined. If not internal driver functions are used which cause compilation failures.
