From a409a8b85ee337250043aa0c031a31b3a6639e74 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Tue, 19 Jan 2016 09:16:21 -0600 Subject: [PATCH] Revert "arm: socfpga: set the fpga global bit to disable HPS to FPGA signals" Apparently, the logic for the FPGA global bit is not universal between Gen5 and Gen10 devices is not the same. Disabling this bit, while applicable to Gen10 devices, will break FPGA programming on Gen5 devices.
