kernel.fitimage.bbclass: remove ramdisk_ctype

2019-09-27T12:02:17+00:00

set in the ramdisk node the compression property always to "none", as U-Boot nowadays since commit: b1307f884a91 ("fit: Support compression for non-kernel components (e.g. FDT)") decompress non kernel components. Setting compression to the used comression algorithm now, will end in fail of your kernel boot with the ramdisk. This issue is fixed since commit: bddd98573465 ("fit: Do not automatically decompress ramdisk images") which now prints a warning in U-Boot, instead of decompressing the ramdisk, but we should setup compression property correct.

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

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.
