13947f43c9 net: fec_mxc: add PHYLIB support
Surround non PHYLIB routines miiphy_restart_aneg
and miiphy_wait_aneg with ifndef CONFIG_PHYLIB.
When later PHYLIB is required it is easy to delete
the non-PHYLIB code. This separation idea
came from Andy Fleming.

fec_miiphy_read, and fec_miiphy_write changed to
fec_phy_read, and fec_phy_write with argument changes.

Deprecated miiphy_register is no longer used. Both
old and new PHYLIB code now use mdio_register.

Cleanup some debug prints.

Inline function fec_miiphy_fec_to_eth is no longer necessary.
Moved to the single call location.

9e27e9dca1 FEC: Allow multiple FECes
This patch allows user to register multiple FEC controllers. To preserve
compatibility with older boards, the mxcfec_register() call is still in place.
To use multiple controllers, new macro is in place, the mxcfec_register_multi(),
which takes more arguments. The syntax is:

mxcfec_register_multi(bd, FEC ID, FEC PHY ID on the MII bus, base address);

To disable the fecmxc_register() compatibility stuff, define the macro
CONFIG_FEC_MXC_MULTI. This will remove the requirement for defining IMX_FEC_BASE
and CONFIG_FEC_MXC_PHYADDR.

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.

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.
