commit daed610c48b0720ec8b5b2afb719b3247675708d Author: Timothy Pearson tpearson@raptorengineeringinc.com Date: Fri Jul 3 17:16:22 2015 -0500
src/southbridge/amd/sr5650: Always configure lane director on startup
On the ASUS KGPE-D16 it was noted that the pin straps did not properly configure the lane director hardware, causing link training failure on NIC B. Forcing coreboot to always reconfigure the lane director on startup resolves this problem.
