This PR adds experimental u-boot support using new wolfTPM2 IO Callback and instructions for U-boot.

Partially tested.

@dgarske this U-boot support is similar to our Barebox support, it requires manual steps on U-boot side that I tried to explain in README.md file.

I think it is ready for review.

@dgarske all peer feedback taken in.

Good catch on the SPI release. Thanks!

@tomoveu , can you point us to the U-Boot fork with your changes?

tomoveu commented 2 years ago

@dgarske let me clean it up a bit and I will drop a link. Should we add it into the README as well?
