This change introduces a Qemu board for an Armv7-A target executing with OP-TEE secure world services. The target Linux based normal world embeds the standard minimal filesystem with OP-TEE non-secure components embedded files from OP-TEE test, examples and benchmark packages. qemu_arm_vexpress_tz_defconfig differs from qemu_arm_vexpress_defconfig. Supporting both secure and non-secure worlds on the Arm target mandates a secure world, here OP-TEE OS, and a bootloader to boot both worlds, here TF-A (boot/arm-trusted-firmware). Here non-secure Linux kernel is booted through U-boot TF-A bootloader (BL1/BL2) => OP-TEE (BL32) => U-boot (BL33). | Executes as secure | Secure | Execs as Non-secure | Loads BL32/BL33 in RAM | Jumps to BL33 | Always booted after | Jumps to BL32 once done | as Non-secure | secure world inits Vexpress and vexpress-tz defconfigs also differs in that Qemu emulates a Cortex-A9 in the former and a Cortex-A15 in the later. Cortex-A15 is the Armv7-A CPU used in upstream TF-A and OP-TEE OS packages hence selected here. Defconfig adds a fragment to the Linux kernel native configuration to enable OP-TEE driver support. Defconfig adds a fragment to the U-Boot native configuration set boot command, enable semihosting and remove U-Boot persistent environment storage support. The defconfig also enables build of the Qemu emulator in case the system installed Qemu does not yet support CPU TrustZone secure state.
