Error reporting is one important private feature, it reports error detected on port and accelerated function unit (AFU). It introduces several sysfs interfaces to allow userspace to check and clear errors detected by hardware.

This patch introduces userclock sysfs interfaces for AFU, user could use these interfaces for clock setting to AFU. Please note that, this is only working for port header feature with revision 0, for later revisions, userclock setting is moved to a separated private feature, so one revision sysfs interface is exposed to userspace application for this purpose too.

After valid PR bitstream is programmed and the port is enabled, then this MMIO region could be accessed. This patch adds support to enumerate the AFU MMIO region and expose it to userspace via mmap file operation. Below interfaces are exposed to user: Sysfs interface: * /sys/class/fpga_region/<regionX>/<dfl-port.x>/afu_id Read-only. Indicate which PR bitstream is programmed to this AFU. Ioctl interfaces: * DFL_FPGA_PORT_GET_INFO Provide info to userspace on the number of supported region. Only UAFU region is supported now. * DFL_FPGA_PORT_GET_REGION_INFO Provide region information, including access permission, region size, offset from the start of device fd.
