[U-Boot] [PATCH 00/13] Add saveenv support for STM32MP1

[Patrice Chotard]

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


Patrice Chotard (10):
  stm32mp1: support dynamic MTDPARTS
  env: ext4: Allow overriding interface, device and partition
  board: stm32mp1: Add env_ext4_get_dev_part() and env_ext4_get_intf()
  env: allow ENV_IS_NOWHERE with other storage target
  stm32mp1: Add env_get_location()
  mtd: Fix get_mtdparts()
  stm32mp1: Move ENV_SIZE to Kconfig
  configs: stm32mp15: Enable ENV_IS_IN_UBI
  configs: stm32mp15: Enable ENV_IS_SPI_FLASH
  stm32mp1: Update env_get_location for NOR support

Patrick Delaunay (3):
  stm32mp1: activate NAND and NOR support on EV1
  env: enable saveenv command when one CONFIG_ENV_IS_IN is activated
  configs: stm32mp15: Enable ENV_IS_IN_EXT4 and all relative flags
