You're welcome.

You will probably have to make a few adjustments, but that should not
be too heavy. There have been many changes in the infrastructure of
U-Boot lately, mainly revolving around the integration of Kconfig,
Kbuild and the driver model. At worst, you should have to upgrade your
config / make / maintainers files, and maybe adjust your code for a
few changes in the driver APIs. To have an idea:
