Subject: [PATCH 3/4] memtest: exclude page starting at address 0.
Date: Fri, 28 Feb 2014 12:58:54 +0000	[thread overview]
Message-ID: <1393592335-9871-4-git-send-email-renaud.barbier@ge.com> (raw)
In-Reply-To: <1393592335-9871-1-git-send-email-renaud.barbier@ge.com>

memtest fails when a reserved sdram region is at the bank start at
address 0. This patch supports the exclusion of memory region at
the bank start.

Tested on P2020RDB and DA923RC, qemuarm versatilepb.
