The STM32MP_USB_PROGRAMMER and STM32MP_UART_PROGRAMMER flags are no more
used when compiling BL32.
The services STM32_SMC_READ_ALL and STM32_SMC_WRITE_ALL should then be
always present in the code. They can only be used when booting from serial
device, so a dedicated check is added.
This adds 1.6kB of code.

Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

TF-A implements Arm interface standards, including:

The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
