Subject: [PATCH 04/13] ARM: at91: setup.c: use endian agnostic IO functions
Date: Wed, 18 Mar 2015 15:53:03 +0000 [thread overview]
Message-ID: <1426693992-31163-5-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1426693992-31163-1-git-send-email-ben.dooks@codethink.co.uk>
Use the endian agnostic IO accessors in setup.c to avoid issues if
running on an big endian capable cpu
