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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
