# TOP_DIR - workspace root directory
# CROSS_COMPILE - PATH to GCC including CROSS-COMPILE prefix
# PARALLELISM - number of cores to build across
# LINUX_BUILD_ENABLED - Flag to enable building Linux
# LINUX_PATH - sub-directory containing Linux code
# LINUX_ARCH - Build architecture (arm64)
# LINUX_CONFIG_LIST - List of Linaro configs to use to build
# LINUX_CONFIG_DEFAULT - the default from the list (for tools)
# LINUX_{config} - array of linux config options, indexed by
# path - the path to the linux source
# defconfig - a defconfig to build
# config - the list of config fragments
# TARGET_BINS_PLATS - the platforms to create binaries for
# TARGET_{plat} - array of platform parameters, indexed by
# fdts - the fdt pattern used by the platform
# UBOOT_UIMAGE_ADDRS - address at which to link UBOOT image
# UBOOT_MKIMAGE - path to uboot mkimage
# LINUX_ARCH - the arch
# UBOOT_BUILD_ENABLED - flag to indicate the need for uimages.
#
# LINUX_IMAGE_TYPE - Image or zImage (Image is the default if not specified)
