What's the most easy way to write to a given register from userspace?
Eg. I want to write to the EVT0 register, at the end of my rc file. (I need to do this in order to reset my uboot boot limit counter.)
This is a very simple operation. Could look like something like:
Very simple. I only need to do it once. After boot.
I could ofc build the famous *EVT0 char driver*. But it seems to be a bit wasteful and troublesome.
Is there another way?
