Subject: [PATCH 2/8] Makefile: generate a barebox-flash-image link
Date: Sun, 12 Aug 2012 16:22:40 +0200	[thread overview]
Message-ID: <1344781367-13547-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1344781367-13547-1-git-send-email-s.hauer@pengutronix.de>

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.

To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.
