You could set the version in the platformconfig to 4.1 and use symlinks to switch: configs/platform/kernelconfig-4.1 -> kernelconfig-4.1-foo configs/platform/patches/linux-4.1 -> linux-4.1-foo You could use the kernel template to build both kernels at the same time. You'll need to tweak the rules a bit: KERNEL_FOO := linux-$(KERNEL_FOO_VERSION)-foo KERNEL_FOO_DIR := $(BUILDDIR)/$(KERNEL_FOO) KERNEL_FOO_URL := .../linux-$(KERNEL_FOO_VERSION).$(KERNEL_FOO_SUFFIX) KERNEL_FOO_SOURCE := $(SRCDIR)/linux-$(KERNEL_FOO_VERSION).$(KERNEL_FOO_SUFFIX) You won't be able to use the kernel-url macro, just use a normal URL. Basically, KERNEL_FOO must contain the '-foo' because the patch dir is derived from this. And KERNEL_FOO_URL and KERNEL_FOO_SOURCE must point to the upstream tarball.
