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.

The Linux custom configuration is dumped from the vexpress_defconfig
with few added fragments: OP-TEE driver and 9p for virtual filesystem to
ease file manipulation and exchanges through Qemu virtfs support.

The standard way for booting OP-TEE with a non-secure world companion
use the Arm Trusted Firmware-A as bootloader. OP-TEE OS provides the
BL32 image and U-boot the BL33 image. The proposed board enables OP-TEE
and U-boot build for this. However package boot/arm-trusted-firmware
needs few change support building Armv7-A targets.

Therefore the proposed board allows one to build the images but not
yet to run the target with the built Qemu host tool.

+Board qemu_armv7a_tz_virt builds a Qemu Armv7-A target with
+OP-TEE running in the TrustZone secure world setup and a Linux based
+OS running in the non-secure world.
+
+This setup is usually booted with the Arm Trsuted Firmware-A (TF-A from
+package boot/arm-trusted-firmware). However the current Buildroot package
+needs few changes to build TF-A for OP-TEE support.
+
+Until BR arm-trusted-firmware is updated this board allows one to only
+build the secure and non-secure boot images if not the BIOS for the Qemu
+host.
