Yes, and for the U-Boot SPL flow, my u-boot_%.bbappend then has this:
DEPENDS += "arm-trusted-firmware"
# Required to the bl31.bin into the U-Boot FIT, as our kernel won't
boot without ATF.
do_compile_prepend() {
cp -aL ${DEPLOY_DIR_IMAGE}/arm-trusted-firmware.bin ${B}/b31.bin
}
# EXTRA_OEMAKE seems not respected, DEVICE_TREE is not set, and PM_CFG
not supported yet in OE
do_configure_append() {
cd ${B}
sed -i
's,^CONFIG_DEFAULT_DEVICE_TREE.*,CONFIG_DEFAULT_DEVICE_TREE="zynqmp-zcu102-rev1.0",g'
.config
sed -i 's,^CONFIG_OF_LIST.*,CONFIG_OF_LIST="zynqmp-zcu102-rev1.0",g' .config
sed -i
's,^CONFIG_PMUFW_INIT_FILE.*,CONFIG_PMUFW_INIT_FILE="${PMU_FIRMWARE_DEPLOY_DIR}/${PMU_FIRMWARE_IMAGE_NAME}.bin",g'
.config
sed -i
's,^CONFIG_ZYNQMP_SPL_PM_CFG_OBJ_FILE.*,CONFIG_ZYNQMP_SPL_PM_CFG_OBJ_FILE="${PMU_FIRMWARE_DEPLOY_DIR}/${PMU_CFG_OBJ_IMAGE_NAME}.bin",g'
.>
}
# SPL no longer support legacy images, we need to build a FIT image
do_deploy_append() {
install -D -m 644 ${B}/u-boot.itb ${DEPLOYDIR}/u-boot.itb
}
Another worry:
Would this still work with a multiconfig setup, as described in
https://github.com/Xilinx/meta-xilinx/blob/master/meta-xilinx-bsp/README.building.md?
I think meta-microblaze layer should *only* be in the pmu
(multi)config, but AFAIK, we do not support a different bblayers.conf
for a multi(config).
Regards,
Leon.
