barebox: support auxiliary config build
Adds support to build barebox with an auxiliary config. This is useful for building an SPL (Secondary Program Loader) in addition to the traditional TPL (Tertiary Program Loader). The Beaglebone Black for example has two barebox configurations: - am335x_defconfig builds the full barebox bootloader with device tree - am335x_mlo_defconfig builds the smaller MLO bootloader that loads the full barebox bootloader from the eMMC or SD card. Tested with the following defconfig: # architecture BR2_arm=y BR2_cortex_a8=y BR2_ARM_EABIHF=y # system BR2_TARGET_GENERIC_HOSTNAME="beaglebone" BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_DEVTMPFS=y BR2_TARGET_GENERIC_REMOUNT_ROOTFS_RW=y # filesystem BR2_PACKAGE_AM33X_CM3=y BR2_TARGET_ROOTFS_EXT2=y BR2_TARGET_ROOTFS_EXT2_4=y # bootloader BR2_TARGET_BAREBOX=y BR2_TARGET_BAREBOX_BOARD_DEFCONFIG="am335x" BR2_TARGET_BAREBOX_IMAGE_FILE="images/barebox-am33xx-beaglebone.img" BR2_TARGET_BAREBOX_CUSTOM_ENV=y BR2_TARGET_BAREBOX_CUSTOM_ENV_PATH="board/beaglebone/barebox/barebox.env" BR2_TARGET_BAREBOX_AUX=y BR2_TARGET_BAREBOX_AUX_BOARD_DEFCONFIG="am335x_mlo" BR2_TARGET_BAREBOX_AUX_IMAGE_FILE="images/barebox-am33xx-beaglebone-mlo.img" # kernel BR2_LINUX_KERNEL=y BR2_LINUX_KERNEL_USE_DEFCONFIG=y BR2_LINUX_KERNEL_DEFCONFIG="omap2plus" BR2_LINUX_KERNEL_ZIMAGE=y # use the barebox built-in dtb # BR2_LINUX_KERNEL_DTS_SUPPORT is not set Signed-off-by: Pieter Smith <pieter@boesman.nl> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
