Subject: [PATCH RESEND 2/7] ARM: socfpga: enable big endian for secondary core(s)
Date: Wed, 25 Mar 2015 11:27:47 +0000	[thread overview]
Message-ID: <1427282872-10563-3-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1427282872-10563-1-git-send-email-ben.dooks@codethink.co.uk>

Update the secondary code to allow the secondary boot to work when the
system is running big endian.
