boot/uboot: fix missing host-openssl for i.MX28 target

2016-05-25T15:09:22+00:00

Building an U-Boot image for the i.MX23 or i.MX28 target requires to run the bootloaders 'mxsimage' tool on the host. As mxsimage needs unconditionally OpenSSL, building U-Boot for those targets fails if it is not available on the host: tools/mxsimage.c:18:25: fatal error: openssl/evp.h: No such file or directory #include Add the required dependency 'host-openssl' to all the different U-Boot image types used to build a bootloader image for an i.MX23/i.MX28 target. Also pass HOST_CFLAGS and HOST_LDFLAGS to the U-Boot build process so the right -I/-L options will be used to find OpenSSL.

barebox: add an option to embed environment image

2016-05-06T13:48:01+00:00

Barebox provides an option to embed a custom environment image into barebox binary. This image will be used, when the environment found in the environment sector is invalid. Both embedded and external images can be used together, so having both options at the same time is justified. This patch sets barebox Kconfig option CONFIG_DEFAULT_ENVIRONMENT_PATH to user specified path. This way one can use such BR's variables like BR2_EXTERNAL, TOPDIR etc. to provide paths to custom environment folders. Cc: Pieter Smith Signed-off-by: Yegor Yefremov Signed-off-by: Thomas Petazzoni

uboot: ensure u-boot-dtb.img gets built if enabled

2016-05-05T09:31:39+00:00

u-boot-dtb.img only gets built by default (all target) if CONFIG_OF_SEPARATE _AND_ CONFIG_SPL_FRAMEWORK are enabled. Certain SoCs (E.G. Action Semi S500) use a proprietary first level bootloader instead of u-boot SPL, but still use u-boot-dtb.img as the first level bootloader parses the uImage header for size/loadaddr. Ensure u-boot-dtb.img gets built if enabled by explicitly listing it as a u-boot make target (next to all) to support such setups. Signed-off-by: Peter Korsgaard

syslinux: fix boot hang when host-gcc is 5.3

2016-05-01T20:22:11+00:00

Syslinux uses the host version of gcc to build to bootloader. On systems with gcc 5.3, this results in a bootloader that hangs. This issue has been addressed in upstream syslinux, but an official release has not been made yet. This commit adds the upstream patch to fix the issue. Most likely fixes bug #8866.

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: extract package name argument

2016-04-24T15:47:02+00:00

No functional changes: Extracts an argument to the inner-barebox-package function to automatically determine the uppercase package name. This is needed to support a 2nd config build. This results in the following renaming: 'BAREBOX' -> '$(1)' All barebox packages are meant to be built from the same sources, so related KConfig variables (origin, version and patch directory) are not extracted.

barebox: introduce barebox-package function

2016-04-24T15:45:24+00:00

No functional changes: Introduces a barebox-package function towards re-use by a 2nd config build. Because the function is meant to be called from within a $(eval), all instances of '$' has to be escaped. I.e. rename '$' -> '$$'. Signed-off-by: Pieter Smith Signed-off-by: Thomas Petazzoni

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
