This is still work in progress...

Please note that new code added to U-Boot shall have GPL2.0+, i. e.
GPL2.0 only is only accepted if the code is borrowed from other,
already existing projects (like the linux kernel).

See [1]

There are two parts here;  first, you must define the exact license
terms.  GPL is already defined in SPDX, so that is no isse.  But you
have to add your proprietary license to the Licenses/ directory, and
define a Unique License Identifier for it (which you should also
submit to the SPDX project for official registration).  Second, in the
SPDX-License-Identifier: line, both license IDs get listed, separated
by white space.

Best regards,

Real computer scientists despise the idea of actual  hardware.  Hard-
ware has limitations, software doesn't. It's a real shame that Turing
machines are so poor at I/O.
