28c064e66b board: stm32mp1: Update power supply check via USB TYPE-C
Add 2 new checks:
 - detect when USB TYPE-C cable is not plugged correctly.
   In this case, GND and VBUS pins are connected but not CC1
   and CC2 pins.

 - detect is an USB Type-C charger supplies more than 3 Amps
   which is not compliant with the USB Type-C specification

In these 2 situations, stop the boot process and let red led
blinks forever.

e5c38fdd3a stm32mp1: Update env_get_location for NOR support
Update env_get_location() to be able to save environment into
NOR (SPI_FLASH).

Series-cc: pde, cke, pch, uboot-stm32

Cover-letter:
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
    environment
  - updates rule to set ENV_IS_NOWHERE value
  - introduce ENV_IS_IN_DEVICE
END

7f90cd6150 board: stm32mp1: Add env_ext4_get_dev_part() and env_ext4_get_intf()
This allows to :
- select the current device to save the environment file
- select the correct EXT4 boot device instance
  and partition to save the environment file.

For EXT4, device is mmc, device instance is 0 for sdcard or 1 for eMMC.
The partition is set to "auto" to select the first partition with
bootable flag.

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.

395f12976c Board: stm32mp1: Add supply current boot information
For DK1/DK2 boards, check if power supply provides enough current
to allow the board to boot correctly.
ADC@0 channel 18 and 19 are connected to USB type-C CC1 and CC2
signals. The table below shows the behavior for different range of
CC1 or CC2:

  range       | power supply | red led |          console message
  (Volts)     |   (Amps)     | blinks  |
--------------|--------------|---------|-----------------------------------

[1.23 - 0.66[ |     1.5      | 3 times | WARNING 1.5A power supply detected
[0.66 - 0]    |     0.5      | 2 times | WARNING 500mA power supply detected

If detected current is < 3A, red led is kept ON after blinking.

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.
