Subject: [[PATCH v2] 10/11] [V2] memory: samsung: endian fixes for IO
Date: Tue, 21 Jun 2016 11:20:31 +0100	[thread overview]
Message-ID: <1466504432-24187-11-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1466504432-24187-1-git-send-email-ben.dooks@codethink.co.uk>

Use the relaxed versions of the IO accessors to avoid any issues
if running in big endian.
