Subject: [U-Boot] [PATCH 1/2] mx6sabresd: Fix SPL memory description
Date: Thu, 16 Apr 2015 22:11:47 -0300	[thread overview]
Message-ID: <1429233108-23912-1-git-send-email-festevam@gmail.com> (raw)

From: Fabio Estevam <fabio.estevam@freescale.com>

mx6sabresd has four MT41K128M16JT-125 chips. Each memory has 16-bit bus
and 2GiB, so fix the width and density fields accordingly.
