Subject: [PATCH 1/3] kbuild: Add wilddt function
Date: Mon, 7 Jan 2019 19:31:26 +0000	[thread overview]
Message-ID: <7fe1bbe77ddec38678a60e75512dabdd7e97ab1c.1546888138.git.leonard.crestez@nxp.com> (raw)
In-Reply-To: <cover.1546888138.git.leonard.crestez@nxp.com>

Many SOCs have very simple naming conventions for all boards using a
certain chip and long dtb lists can be collapsed using wildcards.

Since this applied to many architectures add a wilddt function to
Kbuild.include. Example usage:

dtb-$CONFIG_SOC_ABC123 += $(call wilddt,abc123-*)
