Subject: [PATCH] ARM: start: fix fdt inside valid memory check
Date: Tue, 26 Nov 2013 17:21:41 +0100 [thread overview]
Message-ID: <1385482901-23057-1-git-send-email-s.hauer@pengutronix.de> (raw)
We want to check whether boarddata contains a valid dtb if it's inside
valid memory. This includes the base of SDRAM, so use '>=' instead of '>'.
