STM32MP15C-ED1 is the child board plugged on EV1 mother board. ED1 can
be used without its mother board with some interface restrictions
(I.e. no USB-C). This change defines the platform flavor. The several
components (optee_os, tf-a, u-boot, linux) already support ED1 DTS file
identifier.

Change post-image.sh script for stm32Mp1 platform to not try to
copy invalid files are symbolic links to DTB files previously built
in the same build environment. This change makes the script more
flexible.

Genimage script configuration had wrong image name on bootfs partition.
Changed the parameter "image" to correct name for the image to be
generated successfully and to allow successful boot on STM32MP157C-EV1
board.

Replace option partition-type with option partition-type-uuid as the
later is intended to GPT partitioning which is what stm32mp1 relies on.
This change prevents genimage tool, since its v13 release, from creating
a hybrid MBR partition table that is not supported by TF-A boot stage
used by the platform.

Usage: set QEMU_PSS_ENABLE=y and adjust QEMU_PSS_HOST_DIR. It also
requires QEMU_VIRTFS_ENABLE to be set to "y".

Also added a buildroot post-script which appends lines to /etc/fstab,
so shared directories can be automatically mounted if
QEMU_VIRTFS_AUTOMOUNT and QEMU_PSS_AUTOMOUNT are set to "y".

Build OP-TEE for STM32MP1 based platforms. Currently supports platforms
STM32MP157A-DK1, STM32MP157C-DK2 and STM32MP157C-EV1 using a SDcard as
boot media.

Default build targets board STM32MP157C-DK2:
# make

One can specify a target board with PLATFORM configuration switch:
# make PLATFORM=stm32mp1-157A_DK1
# make PLATFORM=stm32mp1-157C_DK2
# make PLATFORM=stm32mp1-157C_EV1

Refer to br-ext/board/stmicroelectronics/stm32mp1-tz/readme.txt for
mode information.

TF-A, OP-TEE OS, U-Boot and Linux kernel are built outside Builrdoot.
All other embedded components are built through Buildroot.
Buildroot generates the final SDcard binary image file to be loaded
raw in the target SD card. The image includes a GPT partition table.
See br-ext/board/stmicroelectronics/stm32mp1-tz/genimage-*.cfg
for more details.

Note on U-Boot defconfig: from v2019.10 up to v2020.07-rc2, one shall
use stm32mp15_optee_defconfig. From v2020-rc3 onward, one shall use
stm32mp15_trusted_defconfig. For flexibility, stm32mp1.mk supports both.

Adds the required flags and configuration files to enable Wi-Fi on the
HiKey960 board. The network name and password have to be set in
br-ext/board/hikey960/overlay/etc/wpa_supplicant.conf before building.
Then Wi-Fi can be enabled on the board by running 'ifup wlan0' as root.
