firmware: xilinx: Add debugfs interface2018-09-26T06:47:35+00:00Rajan Vajarajanv@xilinx.com2018-09-12T19:38:39+00:00urn:sha1:b321725257c17335b6a8388530366caa2c581084
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.

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.
