From 75bf1bd7d2f993787d0faa7d6e6534f7e88a2975 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 9 Aug 2019 16:40:39 +0200 Subject: ARM: lpc32xx: allow multiplatform build 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.
