Why can' I access the FPGA to HPS bridges from a Linux user space application

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description Due to tighter security and privileged accesses in ARRIA®  10, the FPGA to HPS bridges are no longer accessible in Linux user space mode.
Resolution In order to access the bridges, users are now required to write a Linux Kernel space driver, that provides the ability to switch the access to the bridges into a secure / privileged access mode, and to pass on the data to the FPGA.
