Hello, I recently got my hands on boardviews of many Asus P8x7x series mainboards, and some offshoots such as Z77-A and Sabertooth Z77, and have also found a way to extract VBT data and the USB port config out of the vendor firmware image (which isn't really a straight image, but what looks like an update capsule), allowing me to attempt something quite ambitious given I only have the P8Z77-M on hand: Bring coreboot to the entire family.
Again because I only have the vendor firmware image and boardview to go by, I will only be able to put out an untested new board patch, hence I am calling for anyone with these boards, that aren't already in the tree, to help me test them, and to get things I can't get out of firmware image, such as HDA verbs and GPIO setup, by running autoport on your board. Additionally, if you have a P8Z77-V (Hello Bill!), please test this patch: https://review.coreboot.org/c/coreboot/+/85413 And if you have a P8Z77-M PRO, please test your serial port, and if changing it to use serial port A like P8Z77-M does, make the serial port work. Now, during my survey of the board family, I found that: 1. They link their power LEDs to only one of two GPIOs on the PCH: 8 or 27. That's easily determined from the boardview. 2. Except for P8C WS which I can't get a boardview for, this family only uses one of two Nuvoton super I/Os: NCT5535D or NCT6779D. 6779 is well known, but I cannot find the datasheet for 5535, and the pinout for the closest thing I can find, NCT5532D, have the pins shifted by approximately 3 pins, and there may be more differences. Does anyone know anything about NCT5535D or can hook me up with a datasheet?
