Subject: [Buildroot] [PATCH v2 3/3] boot/uboot: copy IMX firmware files to uboot package dir
Date: Fri, 10 Sep 2021 16:09:29 +0200	[thread overview]
Message-ID: <20210910140925.28138-4-heiko.thiery@gmail.com> (raw)
In-Reply-To: <20210910140925.28138-1-heiko.thiery@gmail.com>

If the U-Boot image is to be built with binman and one of the i.MX
firmware files (ddr, hdmi) is used, the files are expected in the
toplevel directory.

Signed-off-by: Heiko Thiery <heiko.thiery@gmail.com>

v2:
 - small changes in commit messages (thanks Stephane)
 - use "i.MX 8M" for consistency (thanks Stephane)
