From 773a2d7c55a3d63207841c824d21920bd3683460 Mon Sep 17 00:00:00 2001 From: Padmanabh Ratnakar Date: Sat, 20 Oct 2012 06:04:16 +0000 Subject: [PATCH] be2net: Fix FW flashing on Skyhawk-R FW flash layout on Skyhawk-R is different from BE3-R. Hence the code needs to be fixed to flash FW on Skyhawk-R. Also cleaning up code in BE3-R flashing function. Signed-off-by: Vasundhara Volam Signed-off-by: Padmanabh Ratnakar Signed-off-by: David S.
