Add support of RAM target in flashlayout to load kernel image
("system") and device tree ("filesystem") in DDR with DFU and
start these images.
The flashlayout.tsv is:
- 0x01 fsbl Binary none 0x00000000 tf-a.stm32
- 0x03 ssbl Binary none 0x00000000 u-boot.stm32
P 0x10 kernel System ram0 0xC2000000 uImage.bin
P 0x11 dtb FileSystem ram0 0xC4000000 dtb.bin

stm32mp1: add command stm32prog
Add a specific command stm32prog for STM32MP soc family
witch allows to update the devices on the board with the
STMicroelectronics tool STM32CubeProgrammer
(http://www.st.com/STM32CubeProg).
This command use the same UART STM32 protocol than MCU STM32
with or USB with DFU protocol v1.1 (MCU ST extension are no supported).
The executed actions are based on a tab separated value file
with a stm32 header (see
https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout).
This FlashLayout file is loaded in DDR by TF-A during during a
serial boot or in a virtual device by stm32prog command
and is parsed by U-Boot (see "AN5275: USB DFU/USART protocols used
in STM32MP1 Series bootloaders" for details).

Patrick

Add a support of UAR, using the same UART STM32 protocol
than MCU STM32, see "AN5275: USB DFU/USART protocols
used in STM32MP1 Series bootloaders" for details.

For reliability of boot from NAND/SPI-NAND (with read-disturb issue)
the SSBL can be present several time, when it is indicated in the
flashlayout with "Binary(X)".
The received binary is copied X times by U-Boot on the target.

Dynamically adapt the MTD partitions in NOR/NAND/SPI-NAND when stm32prog
command detects in the parsed flash layout files:
- a fsbl partition in NOR.
- a tee partition in NOR/NAND/SPI-NAND

Add support of partial update, update only some partitions,
and check the coherence of the layout with the existing GPT
partitions (offset and size).

Add support of eMMC device boot partition with
part_id = -1 for offset="boot1"
or = -2 for offset="boot2"
The stm32prog command configures the MMC DFU backend with "mmcpart"
and configure the eMMC (command "mmc bootbus" and "mmc partconf")
when the update is done.

Add support of MMC device (based on DFU_MMC backend)
for SD card and eMMC update.
Create a GPT partitioning on the device.

Add a specific command stm32prog for STM32MP soc family
witch allows to program the boot devices with the tool
STM32CubeProgrammer (http://www.st.com/STM32CubeProg).
This command use the same UART STM32 protocol than MCU
STM32 with or USB with DFU protocol v1.1 (ithe MCU ST
extension are no supported).
The executed actions are based on a tab separated value file
with a stm32 header, the FlashLayout file
(https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout).
This file is parsed by the U-Boot command to:
- initialized the devices
- create the partition table on each device
- initialize the DFU backend to access to not volatile memory
(NOR/NAND/SD/eMMC) or to virtual device (OTP/PMIC)
Up to STM32PROG_MAX_DEV (5) devices can be updated with a FlashLayout.
The communication between U-Boot and STM32CubeProgrammer is done with
the specific alternate configuration (see "AN5275: USB DFU/USART protocols
used in STM32MP1 Series bootloaders" for details).
The command stm32prog is executed when a boot from USB is detected
(selected with bootpins) and we can program the board boot devices with
a simple command (on Windows or Linux):
PC $> STM32_Programmer_CLI -c port=usb1 -w flaslayout.tsv
1/ the ROM code loads TF-A in embedded RAM (DFU or uart)
2/ TF-A loads flashlayout file and U-Boot in DDR (DFU or uart)
3/ U-Boot executes the stm32prog command (DFU or uart)
