abf2678f0f stm32mp1: add trusted boot with TF-A
Add support of trusted boot, using TF-A as first stage bootloader,
The boot sequence is
  BootRom >=> TF-A.stm32 (clock & DDR) >=> U-Boot.stm32

The TF-A monitor provides secure monitor with support of SMC
- proprietary to manage secure devices (BSEC for example)
- PSCI for power

The same device tree is used for STMicroelectronics boards with
basic boot and with trusted boot.

acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

7842b6a91e arm: move SYS_ARCH_TIMER to KConfig
SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch
timer) in U-Boot.
At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards.
Add a proper Kconfig symbol to express this dependency properly,
allowing certain board configuration to later disable arch timer in case
there are any problems with it.

11dfd1a331 stm32mp1: select boot device and partition
Bootrom loads SPL from SDCARD or eMMC
according BootPin selection.

Then SPL loads U-Boot on the same mmc device
with the following predefined GPT partitioning:

on SDCARD: gpt partitioning
  1: SPL
  2: SPL#2
  3: U-Boot
  4: bootable partition

on eMMC:
  The 2 boot partitions are used for SPL (2 copy)
    boot1: SPL
    boot2: SPL#2
  The user partition use gpt partitioning
    1: U-Boot
    2: bootable partition

This patch select the correct SPL partition
(3 for SDCARD on mmc0 and 1 for eMMC on mmc1)
according the BootRom information saved in TAMP register
and based on configuration flasg:
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION
  => for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new)
  => for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot

And the correct boot_targets is selected according the environment
variables boot_device and boot_instance, with preboot command,
to search the bootable partition with kernel on this device
(generic distro support).
