03fb03842a board: st: move type-c stusb1600 controller code in a driver
Migrate the ST Microelectronics STUSB160X Type-C controller code in
a generic I2C driver in st/common, based on Linux one in :
drivers/usb/typec/stusb160x.c

This patch simplifies the stm32mp1 board code and allows to reuse
this STUSB160X driver in other boards.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

954bd1a923 stm32mp: add the command stm32prog
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 uses 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:
- initialize 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 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)

888dc68136 board: stm32mp1: add finished good in board identifier OTP
Update the command stboard to support the updated coding of OTP 59 with
finished good.

The ST product codification have several element
- "Commercial Product Name" (CPN): type of product board (DKX, EVX)
  associated to the board ID "MBxxxx"
- "Finished Good" or "Finish Good" (FG):
  effective content of the product without chip STM32MP1 (LCD, Wifi, …)
- BOM: cost variant for same FG
  (for example, several provider of the same component)

For example
- commercial product = STM32MP157C-EV1
- Finished Good = EVA32MP157A1$AU1

Booth information are written on board and these information is also saved
in OTP59:

bit [31:16] (hex) => Board id, MBxxxx
bit [15:12] (dec) => Variant CPN (1....15)
bit [11:8]  (dec) => Revision board (index with A = 1, Z = 26)
bit [7:4]   (dec) => Variant FG : finished good (NEW)
bit [3:0]   (dec) => BOM (01, .... 255)

The updated command is:
  stboard [-y] <Board> <VarCPN> <Revision> <VarFG> <BOM>

And the displayed STMicroelectronics board identification is:
  Board: MB<Board> Var<VarCPN>.<VarFG> Rev.<Revision>-<BOM>

One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

Add saveenv support for STM32MP1

This series adds saveenv support for STM32MP1 on several boot
devices. STM32MP1 is able to boot on eMMC, sdcard and NOR
(NAND support is not fully supported).

On eMMC and sdcard, environment is saved in EXT4 partition
On NOR, environment is saved in a dedicated partition
On NAND, environment is saved in a UBI volume.

This series:
  - enables NAND and NOR support on ev1 board
  - enables ENV_IS_IN_SPI_FLASH, ENV_IS_IN_UBI, ENV_IS_IN_EXT4
    flags
  - fixes get_mtdparts()
  - allows to override interface, device and partition for ext4

6fe7dd3327 stm32mp1: add stusb1600 support for DK1 and DK2 board
The DK1 and DK2 boards use the USB Type-C controller STUSB1600.
This patch updates:
- the device tree to add the I2C node in the DT
- the board stm32mp1 to probe this I2C device and use this controller
  to check cable detection.
- the DWC2 driver to support a new dt property
  "u-boot,force-b-session-valid" which forces B session and
  device mode; it is a workaround because the VBUS sensing and
  ID detection isn't available with stusb1600.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

9242ece12b ram: stm32: migrate fmc defines in driver file
Migrate all FMC defines from arch/arm/include/asm/arch-stm32f7/fmc.h
to drivers/ram/stm32_sdram.c

This will avoid to add an additionnal arch-stm32xx/fmc.h file when
a new stm32 family soc will be introduced.

which was included in the past by stm32x7 driver and by
stm32f746-disco.c board file.
Since patch 42bf5e7c27 "serial: stm32f7: add device tree support"
this file is no more needed in board file.

1a73bd842e spl: stm32f7: configure for xip booting
With xip booting configuration, we don't need to copy the next image
(U-Boot or linux xipimage) from flash to sdram area.

Flash memory organization is like this:
	spl-U-Boot:	u-boot-spl.bin 	: 0x0800_0000
	U-Boot :	u-boot-dtb.bin	: 0x0800_8000
	linux :		xipImage	: 0x0800_8000

It is also possible to have U-Boot binary & linux binaries configured at
different addresses of flash memory like U-Boot at 0x0800_8000 & linux
xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for
U-Boot as next binary with SPL_OS_BOOT option disabled.
By default, spl is configured to boot linux xipImage.
