Subject: [PATCH 11/14] ARM: lpc32xx: allow multiplatform build
Date: Wed, 31 Jul 2019 21:56:53 +0200	[thread overview]
Message-ID: <20190731195713.3150463-12-arnd@arndb.de> (raw)
In-Reply-To: <20190731195713.3150463-1-arnd@arndb.de>

All preparation work is done, so the platform can finally
be moved into ARCH_MULTIPLATFORM. This requires a small
change to the defconfig file to enable the platform.
