firmware: xilinx: Add Zynqmp firmware driver This patch is adding communication layer with firmware. Firmware driver provides an interface to firmware APIs. Interface APIs can be used by any driver to communicate to PMUFW(Platform Management Unit). All requests go through ATF.

help
Firmware interface driver is used by different
drivers to communicate with the firmware for
various platform management services.
Say yes to enable ZynqMP firmware interface driver.
If in doubt, say N.
firmware: xilinx: Add debugfs interface Firmware-debug provides debugfs interface to all APIs. Debugfs can be used to call firmware APIs with required parameters. Usage: * Calling firmware API through debugfs: # echo "<api-name> <arg1> .. <argn>" > /sys/.../zynqmp-firmware/pm * Read output of last called firmware API: # cat /sys/.../zynqmp-firmware/pm Refer ug1200 for more information on these APIs: * https://www.xilinx.com/support/documentation/user_guides/ug1200-eemi-api.pdf Add basic debugfs file to get API version.
