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 a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.
To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.
On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.
As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.
For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

When we switch to including all linker lists in SPL it is important
to not include commands as that may lead to link errors due to other
things we have already discarded. In this case, we split the code for
supporting the monitor out from the code for loading it.
