Otherwise we don't get the DDROutput overrides and the standalone
core fails to generate when using GMII_MII

Leon Schuermann 109002985a phy/gmii: add model parameter to skip clock buffers & generation
To support a simple GMII simulation, skip clock generation and buffer
logic. This allows to operate a GMII interface over sys_clk. Proper
GMII clocking support can still be added in the simulation, this
should work when setting model = False.

It also sets an attribute "model" such that we can avoid adding
Platform constraints in the rest of the ecosystem (such as
litex/litex/soc/integration/soc.py, add_ethernet and add_etherbone).

Leon Schuermann ea55332d26 Add 64-bit XGMII PHY implementation for 10G Ethernet
Adds support for 64-bit wide XGMII PHYs in LiteEth. A 64-bit wide
XGMII data path is a common method to interconnect multi-gigabit
Ethernet inside FPGAs. This module expects a 64-bit MAC data path,
which is to be added later. It has been tested locally using a
rewritten XGMII module for the LiteX simulator as well as on a KCU116
board.

This work has been inspired by enjoy-digital/liteeth#21 but is
entirely rewritten using Migen FSMs and with respect to
IEEE802.3-2018. Thanks to Florent Kermarrec (@enjoy-digital) and Vamsi
Vytla (@jersey99) for providing the base implementation.

This implementation does not yet support proper 32-bit (DDR) XGMII
PHYs, although support can be easily added by an additional module
which performs the DDR encoding / decoding of the data respectively.

David Sawatzke fd827a545c mac/crc: Simplify MACCRC32
Since only the reg of the widest engine is needed, the rest can be
removed

reverse_bits is also a bit more readable

The range for the engine data could be removed, but it's more
understandable this way

David Sawatzke be492e32de mac/core: Add parameter to change processing domain
Per default, the processing should occur with sys_clk and dw, instead of
the phy parameters since it's not that much larger and allows for easier
