16430fd8c6 configs/qemu_arm_vexpress_tz_defconfig: build start-qemu.sh
When tags was added by commit 011206b2bf
to detect the qemu command line, the qemu_arm_vexpress_tz_defconfig
was ignored due to a build issue.

This build issue has been fixed by previous patches, so we can
enable the runtime testing by adding the tag in the readme.txt
and the post-image script in the defconfig.

Since Qemu from HOST_DIR is now executed directly from BINARIES_DIR,
we can remove all the string before "qemu-system-*".

7dcb9e98b5 board/qemu: remove the Qemu version from readme.txt
The Qemu version present in readme.txt files was needed when
the Buildroot's Qemu defconfig was tested manually using the
qemu-system-<arch> binary already present on the host.

This information is now incorrect since we are using host-qemu
package, currently at 4.2.0 version, to do a runtime test since
0c79350638.

For m68k-q800, we can use the upstream qemu since 4.2.0 release
[1].

So, remove this line from the readme.txt.

a89a3f662c board/qemu/arm-vexpress-tz: fixup GDB config info
Fixes reference path "../build/optee_os-" to "./output/build/optee-os-"
as package is optee-os and symbol file here is reached from BR top
dir and assuming output in output/.

Updates GDB tool name to arm-linux-gdb.

a0971ec7ec configs/qemu_arm_vexpress_tz: Armv7-A emulation with TrustZone services
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.

[Arnout, with the help of Peter: correct spelling mistakes in readme,
 fix U-Boot version to 2019.01, download tarball of TF-A instead of git]
