Create a common set of definitions of address and register values for
ethernet MII phys. A few of the current ethernet drivers have at least
a partial set of these definitions. Others just use hard coded raw
constant numbers.
This initial set is copied directly from the allwin

The network mcf_fec driver emulated receive side method is returning a
result of 0 causing the network layer to disable receive for this emulated
device. This results in the guest only ever receiving one packet.
Fix the recieve side processing to return the number of bytes tha

Add a base set of bit definitions for the standard MII phy "Auto-Negotiation
Link Partner Ability Register" (ANLPAR).
The original definitions moved into mii.h from the allwinner_emac driver
did not define these.

The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very
The following set of patches fixes the emulated ColdFire ethernet fec
driver. There is primarily two problems that need to be fixed.
1. The emulated driver needs to support probing of an attached phy.
It is strait forward to emulate an attached phy, but to avoid using
magic numbers I have f

For the interrupt entry case the sp on entry is used to create the stack

Fill out the code support for the move to/from usp instructions. They are
being decoded, but there is no code to support there actions. So add it.
Current versions of Linux running on the ColdFire 5208 use these instructions.

Some small issues are causing problems with running modern versions of
Linux on the m68k/ColdFire 5208 target. These 3 patches fix those problems.
They are all due to use of more advanced architecture features not used
in older Linux kernels.
