Patrick Williamsc0f7c042017-02-23 20:41:17 -06001# This file is part of U-Boot verified boot support and is intended to be
2# inherited from u-boot recipe and from kernel-fitimage.bbclass.
3#
4# The signature procedure requires the user to generate an RSA key and
5# certificate in a directory and to define the following variable:
6#
7# UBOOT_SIGN_KEYDIR = "/keys/directory"
8# UBOOT_SIGN_KEYNAME = "dev" # keys name in keydir (eg. "dev.crt", "dev.key")
9# UBOOT_MKIMAGE_DTCOPTS = "-I dts -O dtb -p 2000"
10# UBOOT_SIGN_ENABLE = "1"
11#
12# As verified boot depends on fitImage generation, following is also required:
13#
14# KERNEL_CLASSES ?= " kernel-fitimage "
15# KERNEL_IMAGETYPE ?= "fitImage"
16#
17# The signature support is limited to the use of CONFIG_OF_SEPARATE in U-Boot.
18#
19# The tasks sequence is set as below, using DEPLOY_IMAGE_DIR as common place to
20# treat the device tree blob:
21#
Patrick Williams213cb262021-08-07 19:21:33 -050022# * u-boot:do_install:append

24# signing, and kernel will deploy UBOOT_DTB_BINARY after signs it.
25#
26# * virtual/kernel:do_assemble_fitimage
27# Sign the image
28#
29# * u-boot:do_deploy[postfuncs]
