To support optee-os and trusted-firmware-a, update ITS file generation scripts, so users are able to use u-boot FIT image to load u-boot, optee-os and treustred-firmware-a images Add a variable "UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A" to enable trusted-firmware-a image and it is disable by default. Add a variable "UBOOT_FIT_OPTEE_OS" to enable optee-os image and it is disable by default. The ITS file creation looks like as following. 1. Both optee-os and trusted-firmware-a are disabled. ''' /dts-v1/; / { images { uboot { }; fdt { }; }; configurations { default = "conf"; conf { loadables = "uboot"; fdt = "fdt"; }; }; }; ''' 2. Only enable optee-os ''' /dts-v1/; / { images { uboot { }; fdt { }; optee { }; }; configurations { default = "conf"; conf { firmware = "optee"; loadables = "uboot"; fdt = "fdt"; }; }; }; ''' 3. Both optee-os and trusted-firmware-a are enabled ''' /dts-v1/; / { images { uboot { }; fdt { }; atf { }; optee { }; }; configurations { default = "conf"; conf { firmware = "atf"; loadables = "uboot", "optee"; fdt = "fdt"; }; }; }; ''' Signed-off-by: Jamin Lin --- meta/classes-recipe/uboot-sign.bbclass | 91 +++++++++++++++++++++++++- 1 file changed, 90 insertions(+), 1 deletion(-) diff --git a/meta/classes-recipe/uboot-sign.bbclass b/meta/classes-recipe/uboot-sign.bbclass index 7a0b8047e4..d2b1013b93 100644 --- a/meta/classes-recipe/uboot-sign.bbclass +++ b/meta/classes-recipe/uboot-sign.bbclass @@ -91,6 +91,18 @@ KERNEL_PN = "${PREFERRED_PROVIDER_virtual/kernel}" UBOOT_FIT_UBOOT_LOADADDRESS ?= "${UBOOT_LOADADDRESS}" UBOOT_FIT_UBOOT_ENTRYPOINT ?= "${UBOOT_ENTRYPOINT}" +# Trusted Firmware-A (TF-A) provides a reference implementation of +# secure world software for Armv7-A and Armv8-A, +# including a Secure Monitor executing at Exception Level 3 (EL3) +# ATF is used as the initial start code on ARMv8-A cores for all K3 platforms +UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A ?= "0" +UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A_IMAGE ?= "bl31.bin" + +# OP-TEE is a Trusted Execution Environment (TEE) designed as +# companion to a non-secure Linux kernel running on Arm +UBOOT_FIT_OPTEE_OS ?= "0" +UBOOT_FIT_OPTEE_OS_IMAGE ?= "tee-raw.bin" + python() { # We need u-boot-tools-native if we're creating a U-Boot fitImage sign = d.getVar('UBOOT_SIGN_ENABLE') == '1' @@ -237,6 +249,20 @@ addtask uboot_generate_rsa_keys before do_uboot_assemble_fitimage after do_compi # Create a ITS file for the U-boot FIT, for use when # we want to sign it so that the SPL can verify it uboot_fitimage_assemble() { + conf_loadables="\"uboot\"" + conf_firmware="" + + if [ "${UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A}" = "1" ]; then + conf_firmware="\"atf\"" + if [ "${UBOOT_FIT_OPTEE_OS}" = "1" ]; then + conf_loadables="\"uboot\", \"optee\"" + fi + else + if [ "${UBOOT_FIT_OPTEE_OS}" = "1" ]; then + conf_firmware="\"optee\"" + fi + fi + rm -f ${UBOOT_ITS} ${UBOOT_FITIMAGE_BINARY} # First we create the ITS script @@ -289,13 +315,76 @@ EOF cat << EOF >> ${UBOOT_ITS} }; +EOF + if [ "${UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A}" = "1" ] ; then + cat << EOF >> ${UBOOT_ITS} + atf { + description = "ARM Trusted Firmware-A"; + data = /incbin/("${UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A_IMAGE}"); + type = "firmware"; + arch = "${UBOOT_ARCH}"; + os = "arm-trusted-firmware"; + load = <${UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A_LOADADDRESS}>; + entry = <${UBOOT_FIT_ARM_TRUSTED_FIRMWARE_A_ENTRYPOINT}>; + compression = "none"; +EOF + + if [ "${SPL_SIGN_ENABLE}" = "1" ] ; then + cat << EOF >> ${UBOOT_ITS} + signature { + algo = "${UBOOT_FIT_HASH_ALG},${UBOOT_FIT_SIGN_ALG}"; + key-name-hint = "${SPL_SIGN_KEYNAME}"; + }; +EOF + fi + + cat << EOF >> ${UBOOT_ITS} + }; +EOF + fi + + if [ "${UBOOT_FIT_OPTEE_OS}" = "1" ] ; then + cat << EOF >> ${UBOOT_ITS} + optee { + description = "OPTEE OS Image"; + data = /incbin/("${UBOOT_FIT_OPTEE_OS_IMAGE}"); + type = "tee"; + arch = "${UBOOT_ARCH}"; + os = "tee"; + load = <${UBOOT_FIT_OPTEE_OS_LOADADDRESS}>; + entry = <${UBOOT_FIT_OPTEE_OS_ENTRYPOINT}>; + compression = "none"; +EOF + + if [ "${SPL_SIGN_ENABLE}" = "1" ] ; then + cat << EOF >> ${UBOOT_ITS} + signature { + algo = "${UBOOT_FIT_HASH_ALG},${UBOOT_FIT_SIGN_ALG}"; + key-name-hint = "${SPL_SIGN_KEYNAME}"; + }; +EOF + fi + + cat << EOF >> ${UBOOT_ITS} + }; +EOF + fi + + cat << EOF >> ${UBOOT_ITS} }; configurations { default = "conf"; conf { description = "Boot with signed U-Boot FIT"; - loadables = "uboot"; +EOF + if [ -n "${conf_firmware}" ]; then + cat << EOF >> ${UBOOT_ITS} + firmware = ${conf_firmware}; +EOF + fi + cat << EOF >> ${UBOOT_ITS} + loadables = ${conf_loadables}; fdt = "fdt"; }; };
