This series of patches is intended to update the boards based on
stm32mp157, in order to use FIP instead of stm32 to boot. This allows
more recent versions of arm-trusted-firmware to be used instead of being
stuck on v2.5

Notes:
1) When testing arm-trusted-firmware lts-2.8.13 on avenger96, the boot
   is halted with a panic:

		NOTICE:  CPU: STM32MP157AAC Rev.B
		NOTICE:  Model: Arrow Electronics STM32MP157A Avenger96 board
		ERROR:   nvmem node board_id not found
		ERROR:   Product_below_2v5=1:
		ERROR:          HSLVEN update is destructive,
		ERROR:          no update as VDD > 2.7V
		PANIC at PC : 0x2ffee76b

   Therefor, the avenger96 board has only been updated to
   arm-trusted-firmware v2.6

2) Testing arm-trusted-firmware v2.10 on stm32mp157a-dk1 results in a
   boot that hangs as follows:

		NOTICE:  CPU: STM32MP157DAC Rev.Z                                                                           
		NOTICE:  Model: STMicroelectronics STM32MP157A-DK1 Discovery Board                                          
		NOTICE:  Board: MB1272 Var3.0 Rev.C-03

		NOTICE:  SP_MIN: Built : 14:24:58, Dec 18 2023

   For stm32mp157c-dk2, a similar hang:

		NOTICE:  CPU: STM32MP157FAC Rev.Z                                                                           
		NOTICE:  Model: STMicroelectronics STM32MP157C-DK2 Discovery Board                                          
		NOTICE:  Board: MB1272 Var4.0 Rev.C-02                                                                      
		NOTICE:  BL2: v2.10.0   (release):v2.10

   No boards currently use the 'latest' version of arm-trusted-firmware,
   so it has no impact to bump the latest version from v2.7 to v2.10

Marleen Vos (7):
  DEVELOPERS: added marleen.vos@mind.be for boards/configs based on
    stm32mp15
  board/stmicroelectronics: generalise
    BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES regex
  configs/stm32mp157*: bump ATF to v2.6
  boot/arm-trusted-firmware: add config option to use latest lts-v2.8.13
  configs/stm32mp157a_dk1_defconfig: update arm-trusted-firmware to
    lts-v2.8.13
  configs/stm32mp157c_dk2_defconfig: update arm-trusted-firmware to
    lts-v2.8.13
  boot/arm-trusted-firmware: bump latest version to v2.10
