Subject: [U-Boot] [PATCH v2 1/6] arm: mvebu: helios4: mmc: move environment before 1M
Date: Fri, 30 Nov 2018 10:54:54 +0800	[thread overview]
Message-ID: <1543546499-106725-2-git-send-email-aditya@kobol.io> (raw)
In-Reply-To: <1543546499-106725-1-git-send-email-aditya@kobol.io>

Store the environment before 1M into the block device.
This constant is easier to remember, saves a little space,
and is in line with what SolidRun's 2018.01-based fork does for the
clearfog.
