From fe4fce3c521f5d9f3a64c4d06a73a5e6b7324116 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 5 Jun 2013 09:04:57 +0200 Subject: [PATCH 027/203] arm: mvebu: remove hardcoded static I/O mapping Now that we have removed the need of the static I/O mapping for early initialization reasons, and fixed the registers area length that were broken, we can get rid of the static I/O mapping. Only the earlyprintk mapping needs to be set up, using the debug_ll_io_init() helper function.
