Follow-up Comment #4, bug #30757 (project avr-libc):
Firstly, sorry for not responding earlier. I think I missed this bug.
The bug28901 talks about missing CPU_t and GPIO_t definitions only. I think
definitions for CPU and GPIO should not have been removed. Upon that I created
the patch in the first place!
My fix for this would look something like below (taken only for iox128a1.h).
Please review if this looks fine. I shall extend it to rest of xmega header
files.
