Hi,

I'm trying to get GPIO and SPI working on my 8272-based board.

Would anyone know if the following exists?-

1) SPI driver for CPM2-based platforms?
2) GPIO driver for CPM2-based platforms?

Also, has anyone used the gpiolib functionality on the CPM2-based platforms?

Cheers,
Daniel

Hi Sergej,

-did you achieve this using gpiolib.c? If not, then what files and
what kernel are you using? We are trying to get it working for 2.6.27.

This is unfortunate. I guess this means SPI on these boards is not
used by many engineers...

No, sorry- not in u-boot.
