From e19db555b4ac79dafa04cc5ff98bdbff01e19388 Mon Sep 17 00:00:00 2001 From: Daniel Schwierzeck Date: Fri, 21 Nov 2014 23:51:33 +0100 Subject: [PATCH] Kbuild: introduce Makefile in arch/$ARCH/ Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.
