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.

The i.MX25 PDK uses RMII to communicate with its PHY. This patch adds
the ability to configure RMII, based on platform data.

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.

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!
