From b9a6098cf60d8e81a2d6eaccd9b148258992982c Mon Sep 17 00:00:00 2001 From: Aaron Williams Date: Fri, 11 Dec 2020 17:05:58 +0100 Subject: [PATCH] mips: octeon: Add cvmx-helper-cfg.c Import cvmx-helper-cfg.c from 2013 U-Boot. It will be used by the later added drivers to support PCIe and networking on the MIPS Octeon II / III platforms.
