This header file is now only used by files that access internal
environment features. Drop it from various places where it is not needed.

Without newline, the error message appears for non prgrammed OTP boards
looks messsy. Hence add it to look more clean.

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.

At present these functions return 0 on success. For some devices we want
to know how many bytes were transferred. It seems useful to adjust the API
to be more like the POSIX read() and write() functions.
Update these two methods, a test and all users.

Use OTP57 and 58 for MAC address
- OTP57 = MAC address bits [31:0]
- OTP58 = MAC address bit [47:32] stored in OTP LSB's
Use manufacture information in OTP13 to OTP15 to build unique
chip id saved in env variable "serial#"
(used for USB device enumeration)

Add the needed information to enable the debug uart
to have printf before the serial driver probe
(so before probe for clock, pincontrol and reset drivers)
To enable the debug on uart 4 (default console):
+ CONFIG_DEBUG_UART=y
+ CONFIG_DEBUG_UART_STM32=y

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.
