# 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"
