From 323d1f9d5bebfe55e97e23c8094055685665afef Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 22 Sep 2015 00:27:39 +0900 Subject: ARM: uniphier: allow to enable multiple SoCs Before this commit, the Kconfig menu in mach-uniphier only allowed us to choose one SoC to be compiled. Each SoC has its own defconfig file for the build-test coverage. Consequently, some defconfig files are duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and CONFIG_{SOC_NAME}=y. Now, most of board-specific parameters have been moved to device trees, so it makes sense to include init code of multiple SoCs into a single image as long as the SoCs have similar architecture. In fact, some SoCs of UniPhier family are very similar: - PH1-LD4 and PH1-sLD8 - PH1-LD6b and ProXstream2 (will be added in the upcoming commit) This commit will be helpful to merge some defconfig files for better maintainability.
