Could someone please have a look a this patch and approve it?
Should I then still add a new section to the docs regarding the console
behavior for the zynq?
With this patch applied it would be that the baud rate of the fsbl is
overwritten by default to 115200, but can be changed using the termios API
(compared to the currently unchangeable baud rate).
I am not sure if that information is that useful or if people will figure that
out in 2 min anyways.
Best regards,
Jan
