The standard approach here would be to install Linux in a VM and use
this as a more developer-friendly environment.

On the other hand, why do you need mkimage at all?  There is a ton
of tools which can compute a standard CRC32 checksum (which is what
U-Boot uses), and U-Boot also has a "crc" command to verify the
checksum of a certain memory range.  So it may be a little bit more
typing, but the goal can be reached without compiling any new tools.

Shudder... no, we don;t.  We are a 100% Windows-free company :-)

Windows is not exaclty a preferred or even well supported build
environment.  Today it is so easy to run a VM that this is probably
the way you should look at.

Best regards,
