IMHO, idea with a new config makes sense, as besides CONFIG_BOOTM_OPTEE=y we should also add CONFIG_ARMV7_BOOT_SEC_DEFAULT=y and provide appropriate CONFIG_BOOTCOMMAND to boot TEE blob (although we're currently in the middle of transition to distroboot usage by default, where we can handle all this in a boot script instead). > > Thanks, > -- > Ricardo Salveti > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > https://lists.denx.de/listinfo/u-boot Thanks -- Best regards - Freundliche GrĂ¼sse - Meilleures salutations Igor Opaniuk mailto: igor.opan...@gmail.com skype: igor.opanyuk +380 (93) 836 40 67 http://ua.linkedin.com/in/iopaniuk _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
