5ded6bac6c arm: stm32mp: disable console for UART serial boot
For UART serial boot, the console need to be deactivated to avoid issue
with tools STM32CubeProgrammer.

This patch adds also the missing dependency for CMD_STM32PROG_SERIAL,
to allow the silent and disable console. This avoid to add is on
board level for STM32MP15 (with TARGET_ST_STM32MP15X or
TARGET_ST_STM32MP13X)

2662d1728d arm: stm32mp: increase EARLY_TLB_SIZE to 0x10000
Depending on Soc (STM32MP25 vs STM32MP21), the memory map can be
different and it generates a different TLB page table configuration/size.

Increase EARLY_TLB_SIZE to 0x10000 to fix following error message
and panic:

"Insufficient RAM for page table: 0xb000 > 0xa000. Please increase the
size in get_page_table_size()"

8eb535e3b0 smt32mp: add setup_mac_address for stm32mp25
Add a function setup_mac_address() to update the MAC address from the
default location in OTP for stm32mp2 platform.

The max number of OTP for MAC address is increased to 8 for STM32MP25,
defined with get_eth_nb() and checked in setup_mac_address.

The MAC address FF:FF:FF:FF:FF:FF, the broadcast ethaddr, is a invalid
value used for unused MAC address slot in OTP, for example for board
with STM32MP25x part number allows up to 5 ethernet ports but it is not
supported by the hardware, without switch; the associated variable
"enetaddr%d" is not created.

01a701994b stm32mp2: initial support
Add initial support for STM32MP2 SoCs family.

SoCs information are available here :
https://www.st.com/content/st_com/en/campaigns/microprocessor-stm32mp2.html

Migrate all MP1 related code into stm32mp1/ directory
Create stm32mp2 directory dedicated for STM32MP2 SoCs.

Common code to MP1, MP13 and MP25 is kept into
arch/arm/mach-stm32/mach-stm32mp directory :
  - boot_params.c
  - bsec
  - cmd_stm32key
  - cmd_stm32prog
  - dram_init.c
  - syscon.c
  - ecdsa_romapi.c

For STM32MP2, it also :
  - adds memory region description needed for ARMv8 MMU.
  - enables early data cache before relocation.
    During the transition before/after relocation, the MMU, initially setup
    at the beginning of DDR, must be setup again at a correct address after
    relocation. This is done in enables_caches() by disabling cache, force
    arch.tlb_fillptr to NULL which will force the MMU to be setup again but
    with a new value for gd->arch.tlb_addr. gd->arch.tlb_addr has been
    updated after relocation in arm_reserve_mmu().
