Parth Pancholi b8c43968b8 board: toradex: add verdin am62p support 
This adds initial support for the Toradex Verdin AM62P module.

The module consists of an TI AM62P family SoC, a TPS65219 PMIC, a
Gigabit Ethernet PHY, up to 8GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC,
an I2C EEPROM, an RX8130 RTC, plus an optional Bluetooth/Wi-Fi module.

These specific changes adds support for Toradex Verdin AM62P Quad 2GB WB
IT module.

Verdin AM62P Module
===================
- SoM: https://www.toradex.com/computer-on-modules/verdin-arm-family/ti-am62p
- Carrier board: https://www.toradex.com/products/carrier-board/verdin-development-board-kit
Quick Start
-----------
- Setup environment variables
- Get binary-only TI Linux firmware
- Build the ARM trusted firmware binary
- Build the OPTEE binary
- Build U-Boot for the R5
- Build U-Boot for the A53
- Flash to eMMC
- Boot
Setup environment
-----------------
Suggested current toolchains are ARM 11.3 (https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads):
- https://developer.arm.com/-/media/Files/downloads/gnu/11.3.rel1/binrel/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz
- https://developer.arm.com/-/media/Files/downloads/gnu/11.3.rel1/binrel/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu.tar.xz
.. code-block:: bash
$ export CROSS_COMPILE_32=<path/to/arm/toolchain/bin/>arm-none-linux-gnueabihf-
$ export CROSS_COMPILE_64=<path/to/arm64/toolchain/bin/>aarch64-none-linux-gnu-
Get the TI Linux Firmware
-------------------------
.. code-block:: bash
$ echo "Downloading TI Linux Firmware..."
$ git clone -b ti-linux-firmware https://git.ti.com/git/processor-firmware/ti-linux-firmware.git
Get and Build the ARM Trusted Firmware (Trusted Firmware A)
-----------------------------------------------------------
.. code-block:: bash
$ echo "Downloading and building TF-A..."
$ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
$ cd trusted-firmware-a
Then build ATF (TF-A):
.. code-block:: bash
$ export CROSS_COMPILE="$CROSS_COMPILE_64"
$ make PLAT=k3 K3_PM_SYSTEM_SUSPEND=1 TARGET_BOARD=lite SPD=opteed
Get and Build OPTEE
-------------------
.. code-block:: bash
$ echo "Downloading and building OPTEE..."
$ git clone https://github.com/OP-TEE/optee_os.git
$ cd optee_os
Then build OPTEE:
.. code-block:: bash
$ export CROSS_COMPILE="$CROSS_COMPILE_32"
$ export CROSS_COMPILE64="$CROSS_COMPILE_64"
$ make PLATFORM=k3-am62px CFG_ARM64_core=y
Build U-Boot for R5
-------------------
.. code-block:: bash
$ export CROSS_COMPILE="$CROSS_COMPILE_32"
$ export BINMAN_INDIRS=<path/to/ti-linux-firmware>
$ make O=/tmp/verdin-am62p-r5 verdin-am62p_r5_defconfig
$ make O=/tmp/verdin-am62p-r5
Build U-Boot for A53
--------------------
.. code-block:: bash
$ export CROSS_COMPILE=$CROSS_COMPILE_64
$ export BL31=<path/to/atf>/build/k3/lite/release/bl31.bin
$ export TEE=<path/to/optee>/out/arm-plat-k3/core/tee-pager_v2.bin
$ export BINMAN_INDIRS="<path/to/ti-linux-firmware> /tmp/verdin-am62p-r5"
$ make O=/tmp/verdin-am62p-a53 verdin-am62p_a53_defconfig
$ make O=/tmp/verdin-am62p-a53
Flash to eMMC
-------------
.. code-block:: console
=> mmc dev 0 1
=> fatload mmc 1 ${loadaddr} tiboot3.bin
=> mmc write ${loadaddr} 0x0 0x400
=> fatload mmc 1 ${loadaddr} tispl.bin
=> mmc write ${loadaddr} 0x400 0x1000
=> fatload mmc 1 ${loadaddr} u-boot.img
=> mmc write ${loadaddr} 0x1400 0x2000
As a convenience, instead of having to remember all those addresses and sizes,
one may also use the update U-Boot wrappers:
.. code-block:: console
=> tftpboot ${loadaddr} tiboot3.bin
=> run update_tiboot3
=> tftpboot ${loadaddr} tispl.bin
=> run update_tispl
=> tftpboot ${loadaddr} u-boot.img
=> run update_uboot
Boot
