From 4730df02cf236eefeaf00bec197e398ad12cfeaa Mon Sep 17 00:00:00 2001 From: Ronak Desai Date: Mon, 12 Oct 2015 13:53:16 -0500 Subject: uboot: arm64 arch build support For a 64bit arm architecture, Buildroot uses arm64 terminology and from the top-level Makefile KERNEL_ARCH is set to arm64 which is then passed to the uboot build. This causes a compilation issue as uboot uses the top-level system architecture as it's $(ARCH). So arch/$(ARCH)/Makefile doesn't work with arm64 unless we adjust the arch.
