IMHO, presented above description is not enough. I'd prefer to see one
patch which adds the code from linux - including the exact commit
message.

Then, u-boot specific adjustments should be applied in a separate patch.

In that way you would:
1. Avoid #ifdef __UBOOT__
2. Make the process of updating code easier
