barebox: support auxiliary config build

2016-05-01T12:33:57+00:00

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 Signed-off-by: Thomas Petazzoni

barebox: prepare for auxiliarry build

2016-05-01T12:27:45+00:00

No functional changes. In preparation for the auxiliary barebox build, boot/barebox is split into two parts: 1. boot/barebox: - The source and patch specification which are to be shared between the barebox and barebox-aux packages. - The barebox-package function and build logic. 2. boot/barebox/barebox: - The package configuration, fragments, barebox env, etc. - The actual barebox package make instantiation.

barebox: support multi-image-build image selection

2016-04-24T15:36:55+00:00

Support optional selection of the built image filename in a multi-image barebox build. This makes it possible to specify which image to pick in a multi-image barebox config such as the am335x_defconfig. Signed-off-by: Pieter Smith [Thomas: - remove default "", since this is the default for string options - rename the prompt from "Barebox image filename" to "Image filename" - slightly improve the Config.in help text.] Signed-off-by: Thomas Petazzoni
