Inquiry Regarding Exporting GPIO Pins on LS1012A Controller

Hi team,

I am working with the LS1012A controller and would like to export its sysgpio pins in order to connect some devices on our custom baseboard. However, after reviewing the "Layerscape Linux Distribution POC User Guide," I noticed that it mentions there is no support for the GPIO feature on the LS1012A. Additionally, I built the Yocto-Qoriq SDK from the styhead branch, but in the final root filesystem, I could not find the usual export or unexport files, nor was there a gpio folder in the /sys/class/ directory. I am therefore unsure how to export the sysgpio pins on this platform. Could you please advise on how to proceed?

Please refer to the following document about how to use GPIO in Linux filesystem.
