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>

the _defconfig suffix.

help
A space-separated list of configuration fragment files,
that will be merged to the main Barebox configuration file.
config BR2_TARGET_BAREBOX_AUX_IMAGE_FILE
string "Image filename"
help
Name of the generated barebox image, which will be copied to
the images directory.
If left empty, defaults to:
- barebox.bin for barebox versions older than 2012.10.
- barebox-flash-image for later versions.
config BR2_TARGET_BAREBOX_AUX_CUSTOM_ENV

help
Generate a custom environment image. This environment will
contain the variables and scripts to be used at boot by
barebox.
config BR2_TARGET_BAREBOX_AUX_CUSTOM_ENV_PATH
string "Environment path"
depends on BR2_TARGET_BAREBOX_AUX_CUSTOM_ENV
help
Path to the directory containing the custom barebox
environment. Depending on your setup, it will probably be
based on either the content of the defaultenv or
defaultenv-2 directories in the barebox source code, plus
the additions needed. The output will be an image in the
barebox devfs format, stored in the images directory, with
the same name as the directory name given here.
