Description

From: https://github.com/cleverca22/not-os/pull/33

Enable the user-space interface for sysfs that is necessary to program FPGA's PL part. Enable programming using fpga-manager and device-tree overlay.

See: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841645/Solution+Zynq+PL+Programming+With+FPGA+Manager

Test log:

-bash-5.2# echo 0 > /sys/class/fpga_manager/fpga0/flags
-bash-5.2# mkdir -p /lib/firmware
-bash-5.2# cp gateware.bin /lib/firmware/                    
-bash-5.2# echo gateware.bin > /sys/class/fpga_manager/fpga0/firmware
-bash-5.2# cat /sys/class/fpga_manager/fpga0/state
operating

Added patches:

Closes #45.
