We needed to add Xilinx OEM support to package to enable latest Xilinx tools like xmutil. Latest version of xmutil is dependent to freeipmi that contains Xilinx fru patch.

Changes should not impact any existing oem support since it only adds a new capability but it is best to check if existing oem parsing is still working without any issue.

Patch is tested on 2 different kinds of Xilinx devices and it is proven to be working. Here is the console output from one of these devices.
