[U-Boot] [PATCH 2/2] image: Add boot_get_fpga() to load fpga with bootm

Tue May 17 14:59:12 CEST 2016
Add function boot_get_fpga() which find and load bitstream to
programmable logic if fpga entry is present.
Function is supported on Xilinx devices for full and partial bitstreams
in BIN and BIT format.

Tests are running on Sandbox and this support requires FPGA commands to
be enabled that's why I haven't done it.
