Subject: [PATCH v2 net-next 0/4] amd-xgbe: add support for AMD Crater

Add support for a new AMD Ethernet device called "Crater". It has a new
PCI ID, add this to the current list of supported devices in the
amd-xgbe devices. Also, the BAR1 addresses cannot be used to access the
PCS registers on Crater platform, use the indirect addressing via SMN
instead.

Changes since v1:
 - A new cleanup patch is introduced to reorganize the code using helper
   functions.
 - New XGBE_XPCS_ACCESS_V3 type has been introduced handle the Crater
   device XPCS handling.
 - Used FIELD_GET() and FIELD_PREP() helpers

Raju Rangoju (4):
  amd-xgbe: reorganize the code of XPCS access
  amd-xgbe: add support for Crater ethernet device
  amd-xgbe: add support for new pci device id 0x1641
  amd-xgbe: use smn functions to avoid race
