Subject: [PATCH V2] sama5d3x: fix AT91_SMC_CS offset stride
Date: Thu, 29 May 2014 14:44:39 +0200	[thread overview]
Message-ID: <assp.0226f60ff0.1401367479-16179-1-git-send-email-matteo.fortini@gmail.com> (raw)

As stated in section 29.19.32 of SAMA5D3 Series datasheet, to move
from CS(n) to CS(n+1) the stride is 0x14 and not 0x10 as in the
other AT91 CPUs
