[PATCH] IT8712F GPIO resources - coreboot

3 Nov 2008

Add the missing I/O resources for IT8712F GPIOs. (E.g. some LiPPERT
boards need them to switch the com ports from RS232 to RS485.) The PnP
resources should prevent other devices from being mapped at the same
spot, even if no OS driver actively uses them.
The IT8712F manual makes it look like PNP_IO1 had a size/granularity of
1 byte, but that must be a mistake. The Simple-I/O resource has a size
of 5 bytes (1 for each GPIO set 1-5) and trying different addresses
reveals a granularity of 8.

Hi,
yes, I already posted this patch last week, together with 2 others, but
got no response. Now I'll try splitting it up to 2 seperate mails,
hopefully that works better.
Regards,
Jens Rottmann
