kernel-fitimage: introduce FIT_HASH_ALG

2019-06-19T11:46:44+00:00

sanitize fitImage hash algorithm selection with FIT_HASH_ALG switch default hash algorithm from sha1 to sha256 (From OE-Core rev: 8c9d5d59cb1575fac17c461090937df4cbb3d3b5) Signed-off-by: Ayoub Zaki Signed-off-by: Richard Purdie

kernel-fitimage: uboot-sign: Check UBOOT_DTB_BINARY before adding deps

2019-06-12T20:08:52+00:00

Since UBOOT_DTB_BINARY empty means we don't need to inject signatures into the U-Boot DTB, we can remove the dependencies between consumers of these two classes and resolve a circular dependency between u-boot and kernel.

kernel-fitimage: support RISC-V

2019-04-12T12:40:21+00:00

Support RISC-V kernel image, using the "Image" target. This change allows RISC-V support for fitImage via the following flow: OpenSBI -> u-boot (as payload) -> Linux kernel (as fitImage with ramdisk and dtb). This was tested using QEMU RISC-V 64-bit.

kernel-fitimage.bbclass: Introduce a way to provide external dtb

2019-02-26T23:04:31+00:00

Currently kernel-fitimage gets the dtb from KERNEL_DEVICETREE, however there are instances when the DTB file can be generated using other recipes, provide a way to include the DTB instead of inkernel device tree. Add support for external device tree during the creation of fitimage. If virtual/dtb is set using PREFERRED_PROVIDER_virtual/dtb = "devicetree", which inherits the devicetree.bbclass then use the path provided in EXTERNAL_KERNEL_DEVICETREE else use KERNEL_DEVICETREE during fitimage process (From OE-Core rev: 084f4de4dbaf9821516fc0254d35f4fb04311d27) Signed-off-by: Manjukumar Matha Signed-off-by: Richard Purdie

kernel-fitimage.bbclass: Fix the dependency issue while generating fitimage_initramfs

2019-02-18T10:33:13+00:00

When building fitimage_initramfs, the correct depedency is to build after do_bundle_initramfs. We can run into the following dependency issue DEBUG: Python function extend_recipe_sysroot finished DEBUG: Executing shell function do_assemble_fitimage_initramfs aarch64-xilinx-linux-objcopy: 'vmlinux': No such file This happens because initramfs renames vmlinux to vmlinux.bak while generating vmlinux.initramfs, there is a chance that fitimage_initramfs can also start during this process and create the above issue. This patch resolve the dependency issue by running fitimage_initramfs task after do_bundle_initramfs (From OE-Core rev: 8f0bece39a634fce5bd882cbd9e289ea905a0b17) Signed-off-by: Varalaxmi Bingi Signed-off-by: Manjukumar Matha Signed-off-by: Richard Purdie

uboot-sign.bbclass: fix signature and deployment

Fixed: MACHINE = "beaglebone-yocto" KERNEL_CLASSES += "kernel-fitimage" KERNEL_IMAGETYPE_beaglebone-yocto = "fitImage" UBOOT_MACHINE_beaglebone-yocto = "am335x_boneblack_vboot_config" UBOOT_MKIMAGE_DTCOPTS = "-I dts -O dtb -p 2000" UBOOT_SIGN_KEYDIR = "${TOPDIR}/conf" UBOOT_SIGN_KEYNAME = "dev" UBOOT_SIGN_ENABLE = "1" IMAGE_INSTALL_remove = "kernel-image-zimage" $ cd conf $ openssl genrsa -F4 -out dev.key 2048 $ openssl req -batch -new -x509 -key dev.key -out dev.crt $ cd ../ $ bitbake u-boot linux-yocto $ grep signature tmp/deploy/images/beaglebone-yocto/*.dtb Binary file tmp/deploy/images/beaglebone-yocto/u-boot-beaglebone-yocto-2018.07-r0.dtb matches Binary file tmp/deploy/images/beaglebone-yocto/u-boot-beaglebone-yocto.dtb matches Binary file tmp/deploy/images/beaglebone-yocto/u-boot.dtb matches And there would be no signature info when rebuild from sstate: $ bitbake u-boot linux-yocto -cclean $ bitbake u-boot linux-yocto $ grep signature tmp/deploy/images/beaglebone-yocto/*.dtb No result This s because kernel directly edit ${DEPLOY_DIR_IMAGE}/u-boot.dtb, (Note, it is global ${DEPLOY_DIR_IMAGE}, not recipe's DEPLOYDIR), so that the modified info is not in sstate, and would be lost when rebuild from sstate. There are other problems in previouse code: - The u-boot.dtb is provided by u-boot, but edited by kernel during signing, so it should be deployed by kernel rather than u-boot. - The u-boot.do_concat_dtb directly install files to global ${DEPLOY_DIR_IMAGE}, this is incorrect, the ${DEPLOY_DIR_IMAGE} should be installed by do_deploy. - It seems that it assumes do_deploy depends on do_install according the comments, but they have no relationships: # do_concat_dtb is scheduled _before_ do_install as it overwrite the # u-boot.bin in both DEPLOYDIR and DEPLOY_IMAGE_DIR. - The do_concat_dtb should be run after do_compile, but it doesn't have this dependency. Make u-boot install u-boot.dtb to ${datadir}, kernel copies u-boot.dtb from ${STAGING_DATADIR} to ${B} and deploy it can fix the problem.

u-boot: Add mkenvimage tool

2018-11-23T23:35:19+00:00

This utility is used for creation of images containing usable in run-time U-Boot environment. As of today this utility is added per-board like here [1] for Intel Edison board. [1] http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/tree/meta-intel-edison-bsp/recipes-bsp/u-boot/u-boot-tools_2014.04.bb Given there're quite some U-Boot tools that we may want to add later this recipe name switch from "u-boot-mkimage" to generic "u-boot-tools" still for compatibility we provide "u-boot-mkimage" with help of PROVIDES as well as proposed "u-boot-mkenvimage".
