# This file is part of U-Boot verified boot support and is intended to be
|
# inherited from u-boot recipe and from kernel-fitimage.bbclass.
|
#
|
# The signature procedure requires the user to generate an RSA key and
|
# certificate in a directory and to define the following variable:
|
#
|
# UBOOT_SIGN_KEYDIR = "/keys/directory"
|
# UBOOT_SIGN_KEYNAME = "dev" # keys name in keydir (eg. "dev.crt", "dev.key")
|
# UBOOT_MKIMAGE_DTCOPTS = "-I dts -O dtb -p 2000"
|
# UBOOT_SIGN_ENABLE = "1"
|
#
|
# As verified boot depends on fitImage generation, following is also required:
|
#
|
# KERNEL_CLASSES ?= " kernel-fitimage "
|
# KERNEL_IMAGETYPE ?= "fitImage"
|
#
|
# The signature support is limited to the use of CONFIG_OF_SEPARATE in U-Boot.
|
#
|
# The tasks sequence is set as below, using DEPLOY_IMAGE_DIR as common place to
|
# treat the device tree blob:
|
#
|
# * u-boot:do_install:append
|
# Install UBOOT_DTB_BINARY to datadir, so that kernel can use it for
|
# signing, and kernel will deploy UBOOT_DTB_BINARY after signs it.
|
#
|
# * virtual/kernel:do_assemble_fitimage
|
# Sign the image
|
#
|
# * u-boot:do_deploy[postfuncs]
|
# Deploy files like UBOOT_DTB_IMAGE, UBOOT_DTB_SYMLINK and others.
|
#
|
# For more details on signature process, please refer to U-Boot documentation.
