accessing a lan9303 switch with the cpsw driver results in wrong
speed detection, as the switch sets the BMSR_ERCAP in BMSR
register, and follow read of the MII_STAT1000 register fails, as
the switch does not support it. Current code did not check,
if a phy_read() fails ... fix this.

Commit de1d786e (add support for Xilinx 1000BASE-X phy (GTX)) introduced the
checking for ESTATUS_1000_XHALF, but it incorrectly sets the
SUPPORTED_1000baseX_Full flag in this case.
Set the SUPPORTED_1000baseX_Half flag instead.

de1d786 [add support for Xilinx 1000BASE-X phy (GTX)] introduced a
check for the extended status register in order to support
1Gbps-capable PHYs that don't have the 1000BASE-T registers. Since
Extended Status only indicates what the PHY (i.e. the local side) is
capable of, this broke communication with non-1Gbps peers.
Only check the extended status if the 1000BASE-T registers are
actually missing so we don't end up setting speed to 1Gbps even though
the previous test (for the combination of local and peer support for
1Gbps) already indicated we can't do 1Gbps with the current peer.

Adds an ET1011C PHY driver which is derived from the
Linux kernel PHY driver (drivers/net/phy/et1011c.c)
from the v3.9-rc2 tag. Note that an errata workaround
config option is implemented to allow for TX_CLK to be
enabled even when gigabit mode is negotiated. This
workaround is used on the PG1.0 TI814X EVM.

It is useful to be able to try a range of
possible phy addresses to connect.
Also, an ethernet device is not required
to use phy_find_by_mask leading to better
separation of mii vs ethernet, as suggested
by Andy Fleming.

phy_startup() calls the PHY driver's startup function, but it ignores the
return code from that function, and so it never returns any failures.

Boards may have things they want done before or after normal phy config.
Letting the boards call drv->config allows them more flexibilty.

This reverts commit 041c542219.
The lines removed by this commit weren't redundant. The logic is (and
probably should be better commented):
Find the intersection of the advertised capabilities of both sides of
the link (lpa).
From that intersection, find the highest capability we can run at
(that will be the negotiated link).
Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL).
The code will now set phydev->speed to 100, and phydev->duplex to 1,
but this link does not support 100FULL.
Kudos to Andy Fleming <afleming@gmail.com> for binging this to
attention and for the explanation.

The PHY driver was too verbose and corrupted the boot message display
like this:
...
Net: TSEC0 connected to Marvell 88E1111S
TSEC1 connected to Marvell 88E1111S
TSEC0, TSEC1
...
Turn printf() into debug() so we het the expected output again:

The tsec driver had a bunch of PHY drivers already written. This
converts them all into PHY Lib drivers, and serves as the first
set of PHY drivers for PHY Lib.
While doing that, cleaned up a number of magic numbers (though
not all of them, as PHY vendors like to keep their numbers as
magical as possible). Also, noticed that almost all of the
vitesse/cicada PHYs had the same config/parse/startup functions,
so those have been collapsed into one.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)
We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.
We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,
we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.
