From 62afc601883e788f3f22291202d5b2a23c1a8b06 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 17 May 2016 14:03:50 +0200 Subject: [PATCH] image: Add boot_get_fpga() to load fpga with bootm 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.
