[MinnowBoard] GPIO – blocked GPIO requests

[Abdelghani Ouchabane]

Hello,
   is it possible to toggle values of several GPIO lines at the same 
time, such as a data and clock line.

"Since several GPIO lines are often handily placed in the same register, 
it is often actually possible to read or write 8, 16 or 32 GPIO lines at 
the same time. By attaching hardware to lines in the same register.

Thanks
Ghani
