32dbe8c58a cmd: binop: Use hex2bin
Use the new hex2bin function in the binop command instead of converting
the data manually.

29dada9c2e cmd: binop: Use new environment api
Since the binop command was introduced, the environment API was changed.
Use the new API to make the command work again.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

55b2556115 cmd: Add command for calculating binary operations
This patch adds a command that enables the calculation of bit operations
(AND, OR, XOR) on binary data from the command line. Memory locations as
well as the contents of environment variables are eligible as sources
and destination of the binary data used in the operations.

The possible applications are manifold: Setting specific bits in
registers using the regular read-OR-write pattern, masking out bits in
bit values, implementation of simple OTP encryption using the XOR
operation, etc.
