Subject: [PATCH] ARM: mx5: forbid building i.MX51 with any of i.MX50 or i.MX53
Date: Tue, 1 Mar 2011 22:07:28 +0100 [thread overview]
Message-ID: <1299013648-26630-1-git-send-email-u.kleine-koenig@pengutronix.de> (raw)
A config supporting all three SoCs compiles just fine, but the image
is broken because of different PHYS_OFFSETs.
This fix is a bit ugly because the i.MX50/i.MX53 machines simply
disappear in the config system when the first i.MX51 machine is
selected, but the upside is that no additional Kconfig symbol is
needed which would break more configs than this change.
