Commit Message

Skidmore, Donald C Sept. 28, 2016, 11:35 p.m. UTC 
This patch add X553 FW ALEF support for B0.  ALEF is the new unified
FW.  This contains updated register defines for ALEF speed
configuration.  Likewise it also removes the AN_CNTL_8 usage from
the native SFI flow as it is no longer supported by FW.
