+Bintool: fdt_add_pubkey: Add public key to device tree +--------------------------------------------- + +This bintool supports running `fdt_add_pubkey` in order to add a public +key coming from a certificate to a device-tree. + +Normally signing is done using `mkimage` in context of `binman sign`. However, +in this process the public key is not added to the stage before u-boot proper. +Using `fdt_add_pubkey` the key can be injected to the SPL independent of +`mkimage`
