[U-Boot] [RFC PATCH 0/1] GPIO support for Microblaze

[Michal Simek]

Hi Simon,

here is also one small problem if you want to use patman just for one patch
then cover letter contains 0/1 but patch itself doesn't contain 1/1.

I think will be good to just add 1/1 to patch too.

Generated by:
./tools/patman/patman -c 1

Thanks,
Michal
