Shawn Guo b5680e0b59 net/fec: add dual fec support for mx28
This patch is to add mx28 dual fec support. Here are some key notes
for mx28 fec controller.

 - The mx28 fec controller naming ENET-MAC is a different IP from FEC
   used on other i.mx variants.  But they are basically compatible
   on software interface, so it's possible to share the same driver.
 - ENET-MAC design on mx28 made an improper assumption that it runs
   on a big-endian system. As the result, driver has to swap every
   frame going to and coming from the controller.
 - The external phys can only be configured by fec0, which means fec1
   can not work independently and both phys need to be configured by
   mii_bus attached on fec0.
 - ENET-MAC reset will get mac address registers reset too.
 - ENET-MAC MII/RMII mode and 10M/100M speed are configured
   differently FEC.
 - ETHER_EN bit must be set to get ENET-MAC interrupt work.

Baruch Siach 5eb32bd059 fec: add support for PHY interface platform data
The i.MX25 PDK uses RMII to communicate with its PHY. This patch adds
the ability to configure RMII, based on platform data.

Greg Ungerer 5ca1ea23c4 fec: fix definition of 5272 version of FEC_X_DES_ACTIVE register
fec: fix definition of 5272 version of FEC_X_DES_ACTIVE register

The ColdFire 5272 FEC driver has a different register address map
than other users of the FEC driver. And its definition of the
FEC_X_DES_ACTIVE register is incorrect, it should be 0x14.
The fec interface cannot transmit data with the old value.

Greg Ungerer cc462f7df0 m68knommu: fix ColdFire 5272 fec driver hash registers
Renamed the 5272 hash_table registers to match the "grp" hash_table
registers of the other ColdFire parts. They are actually a group hash.
The makes for consistent setup across all ColdFire parts.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
