  PchSmbusDxe.c - PCH SMBus DXE Driver Implementation.

  Reconstructed from the compiled binary of the Intel PCH SMBus host
  controller DXE driver for the Purley/LBG platform (HR650X server).

  Source files (from debug strings):
    PurleySktPkg/SouthClusterLbg/Smbus/Dxe/PchSmbusEntry.c
    PurleySktPkg/SouthClusterLbg/Smbus/Dxe/PchSmbusArp.c
    PurleySktPkg/SouthClusterLbg/LibraryPrivate/PeiDxeSmmPchSmbusCommonLib/PchSmbusExec.c

  Build: HR6N0XMLK, DEBUG_VS2015 X64
  Binary: 45 functions, 0x3160 bytes image

  This driver installs the EFI SMBUS HC PROTOCOL for the Intel PCH
  SMBus controller on Purley/H650X platforms.
