kernel-fitimage: adding support for Initramfs bundle and u-boot script

2021-01-20T00:45:05+00:00

This commit adds Initramfs bundle support to the FIT image in addition to u-boot boot script capability. These new features are selectable. In case of Initramfs, the kernel is configured to be bundled with the rootfs in the same binary (ie: zImage-initramfs-.bin). When the kernel is copied to RAM and executed, it unpacks the Initramfs rootfs. For more information about Initramfs please read: https://www.kernel.org/doc/Documentation/filesystems/ramfs-rootfs-initramfs.txt For more details about the Initramfs bundle and boot script implementation please check the kernel-fitimage.bbclass paragraph in Yocto reference or mega manual. Current limitations: - Initramfs bundle FIT support has been tested on ARM 32-bit - The kernel image type in case of ARM 32-bit is zImage Change-Id: I901bfd899e8d733c5b9a2b6645b1d4748f4b1fda (From OE-Core rev: 19fa415c8769a67b52babd80f71d68bf36a21db2) Signed-off-by: Abdellatif El Khlifi Signed-off-by: Richard Purdie

classes/kernel-fitimage: add ability to sign individual images

2020-12-20T00:03:04+00:00

Add the ability to have the kernel, dtb and ramdisk individually signed by setting FIT_SIGN_INDIVIDUAL = "1". This could be useful if you are intending to verify signatures before using kexec for example.

classes/kernel-fitimage: add ability to add additional signing options

2020-12-20T00:03:04+00:00

Add a UBOOT_MKIMAGE_SIGN_ARGS variable to enable passing additional options to uboot-mkimage when it is run the second time to perform signing. (From OE-Core rev: 8fd7ee7414b45a1feeef7982af3583475902a677) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

classes/kernel-fitimage: allow substituting mkimage command

2020-12-20T00:03:04+00:00

Add a UBOOT_MKIMAGE and UBOOT_MKIMAGE_SIGN variables to allow specifying an alternative uboot-mkimage executable (or wrapper script/function). (From OE-Core rev: aee5bac02eff28a75fa1eee646bc511984013aa4) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

classes/kernel-fitimage: make fitimage_emit_section_config more readable

2020-12-20T00:03:04+00:00

fitimage_emit_section_config() has a number of arguments, add named variables to make the function a bit more readable. (From OE-Core rev: a82340eed3165825c129c1f2b1ebf250e0e699c2) Signed-off-by: Easwar Hariharan Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

classes/kernel-fitimage: add variable for description

2020-12-20T00:03:04+00:00

Add a FIT_DESC variable to make it possible to change how the description is set in the FIT image. (From OE-Core rev: 47c5ea69e1a6c4fd3aa766d5223aff1201a4a1d8) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

kernel-fitimage: generate openssl RSA keys for signing fitimage

2020-10-06T22:14:24+00:00

The keys are only generated if they dont exist. The key generation can be turned off by setting FIT_GENERATE_KEYS to "0". The default key length for private keys is 2048 and the default format for public key certificate is x.509.

kernel-fitimage: build configuration for image tree when dtb is not present

2020-08-08T08:17:48+00:00

This patch adds support for adding configuration node even when dtb is not part of the FIT image. The conf and default node number are therefore changed to point to kernel ID rather than dtb ID when dtb does not exist.

kernel-fitimage: fix devicetree reproducibility

2020-02-14T13:07:23+00:00

Ensure that the order of dtb/dtbo files in the generated fitimage is reproducible. Fixes: 71bfa9838cbf ("kernel-fitimage: Handle overlays in EXTERNAL_KERNEL_DEVICETREE") (From OE-Core rev: 9e4a91b63dd8e0c1708da2ac7de461b35fb0b011) Signed-off-by: Alex Kiernan Signed-off-by: Richard Purdie

kernel-fitimage: Handle overlays in EXTERNAL_KERNEL_DEVICETREE

2020-02-13T12:19:14+00:00

When using EXTERNAL_KERNEL_DEVICETREE, collect DTB overlays too (*.dtbo) as well as iterating down into sub-directories so using the behaviour for naming which matches KERNEL_DEVICETREE.
