From 096947fdab96fd97df47b10b8547382290ef9fcd Mon Sep 17 00:00:00 2001 From: Tony Prisk Date: Mon, 8 Oct 2012 10:23:32 +1300 Subject: arm: vt8500: Fix build warning in uncompress.h This removes a build-time warning in uncompress.h due to incorrectly cast values being passed to readb/writeb. Removed arm/io.h and readb/writeb. Read/write directly to the serial port with a volatile pointer.
