Please ignore patch 1 and patch 2 and don't merge them into u-boot.
I  had noted it in the cover-letter. To be clearer, I will point it out in the
commit messages next time.

The reason to add these two patches is that it will fail to compile without
these two patches and be more convenient for the developers to test the
series.

Best regards,
Hal
