This patch series adds HAB support for i.MX8MQ. This was tested on the NXP i.MX8MQ EVK. Other i.MX8MQ boards should still be supported but will require a lowlevel.c rework similar to this done for the i.MX8MQ. The first part adds the necessary HAB interfaces for i.MX8MQ. Than the ability to read and copy the piggydata to the correct location in DRAM is added. Next imx-image is adjusted to support signing of the i.MX8MQ images. The fourth part is the addition of sha256 to the PBL. This is necessary since only the PBL is authenticated using HAB, the main barebox binary is than authenticated to a sha256sum built into the PBL. Finally the EVK board files are adjusted to the changes. To test, add the following lines to Makefile.imx: FILE_barebox-nxp-imx8mq-evk-signed.img = start_nxp_imx8mq_evk.pblb.psimximg image-$(CONFIG_MACH_NXP_IMX8MQ_EVK) = barebox-nxp-imx8mq-evk-signed.img v2: - Add the -p option to imx-image and use this options to distinguish the different HAB insertion methods. - Add wrappers and rework panic for PBL, allowing the same use in PBL as in barebox. - Rework hab initcalls by moving the status calls under explanation and removing the return variable.
