Subject: [ptxdist] [PATCH] flashbench: Fix error when flashbench is not selected
Date: Thu, 22 Mar 2012 09:17:31 +0100	[thread overview]
Message-ID: <1332404251-1245-1-git-send-email-bernhard@bwalle.de> (raw)
In-Reply-To: <20120321231859.GQ20481@pengutronix.de>

When flashbench is not selected in "ptxdist menuconfig", then
$(PTXCONF_FLASHBENCH_MAX_BUFSIZE) is undefined. In that case, the expr
call fails.

Fix the problem by delaying the evaluation of FLASHBENCH_MAKE_OPT until
it's really needed, i.e. when flashbench has been selected.
