8ef583a035 miiphy: convert to linux/mii.h
The include/miiphy.h header duplicates a lot of things from linux/mii.h.
So punt all the things that overlap to keep the API simple and to make
merging between U-Boot and Linux simpler.

e9319f111d drivers/net/fec_mxc.c: write mac address in init
Call fec_set_hwaddr in init routine to setup MAC address so when ethaddr is set
late via setenv the change will propagate to the hw.

f699fe1e1f net,fec: Shorten device name as done for other drivers
After discussion on the ML it is suggested to drop unrequired
and not useful characters from the device name.
This patch changes the name for the fec_mxc driver from
"FEC_MXC" to "FEC".

c179a2896e fec_mxc: incomplete error handling
fec_init() will only allocate fec->base_ptr if it is non-NULL. But
the cleanup routine on error will free the pointer without setting
it to NULL. This means that a later call to fec_init() would result
in using an invalid pointer.

651ef90fa6 mxc_fec: avoid free() calls to already freed pointers.
Sometimes, inside NetLoop, eth_halt() is called before eth_init() has
been called. This is harmless except for free() calls to pointers
which have not been allocated yet.

This patch initializes those pointers to NULL and allocates them only
the first time. This way we can get rid of free calls in halt callback.

This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.

e8f1546a88 mxc_fec: fix some erroneous PHY accesses.
This patch fixes erroneous access to the ethernet PHY which broke the driver.
1. Selector field in the auto-negotiation register must be 0x00001 for
using 802.3, not 0x00000 which is reseved.
2. Access to the PHY address specified by CONFIG_FEC_MXC_PHYADDR, not
0x0 fixed address.

This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.

Now using proper defines for auto-negotiation register.
