[PATCH 0/3] fpga: fpga-mgr: Add support for DebugFS for FPGA Manager Framework

[adrian.ho.yin.ng]

From: Adrian Ng Ho Yin <adrian.ho.yin.ng@intel.com>

Hi,

A DebugFS for the FPGA Manager Framework is implemented which supports 
read/write functionality for the FPGA image firmware file to program for 
debugging purposes. To facilitate in usage a documentation for debugFS is 
added. A debugFS interface is extended for setting the maximum time in 
microseconds for the FPGA to go to the operating state after the region 
has been programmed.

There were some discussion about the FPGA reprograming user interface in
resent years. For FPGA framework, a well designed user interface is
needed rather than a debug one. As is stated by the Patch #2, the FPGA
reprograming should take care of the running devices on that FPGA
region, or system breaks.
