[PATCH 0/5] stm32mp1: handle TF-A boot with FIP

[Patrick Delaunay]

In next TF-A version the stm32mp1 platform will support the Firmware
Image Package (FIP) [1], a container filled with:
- the U-Boot binary = u-boot-nodtb.bin
- the U-Boot device tree = u-boot.dtb
- the Secure OS (OP-TEE) or the secure monitor (SP_MIN)

Upstream is in progress on TF-A side.

Each part of the FIP is loaded by TF-A BL2 and U-Boot
is executed with its device tree address as parameter (nt_fw_dtb = r2
introduced by commit 4ac345220afa ("board: stm32mp1: use FDT address
provided by TF-A at boot time")

This FIP container simplifies the OP-TEE management (same number of partition
with or without OP-TEE, OP-TEE dynamically updates the U-Boot device tree
to add the required OP-TEE nodes) and allow support of generic TF-A
features as PKI [2].

This serie allows to generate U-Boot configured for the TF-A BL2 image
types:
- STM32IMAGE: stm32mp15_trusted_defconfig (current behavior)
- FIP: stm32mp15_defconfig (NEW)

The FIP will be the STMicroelectronics recommended image type for
STM32MP15x and the STM32IMAGE support should be marked deprecated in a
future TF-A release or even removed.

To prepare this migration, the serie move all the specific code or
device tree nodes for TF-A load of STM32IMAGE under compilation
flag CONFIG_STM32MP15x_STM32IMAGE.
