From b2d32f03e67cc9b0ad16fc1fff87edf90f059883 Mon Sep 17 00:00:00 2001 From: Daniel Pieczko Date: Fri, 20 Sep 2013 16:45:10 +0100 Subject: sfc: Increase MCDI status timeout to 250ms The SFC9120 MC firmware often takes longer than 20ms to reboot and update the warm boot count in BIU_MC_SFT_STATUS_REG. A timeout of 250ms is very generous for an MC reboot.
