ddcd1f3084 net: phy: introduce a quirk PHY_FLAG_BROKEN_RESET
Current driver always performs a phy soft reset when connecting the phy
device, but soft reset is not always supported by a phy device, so
introduce a quirk PHY_FLAG_BROKEN_RESET to let such a phy device to skip
soft reset. This commit uses 'flags' of phy device structure to store the
quirk.

b18acb0a11 drivers/net/phy: introduce phy_set_supported()
This new function will allow MAC drivers to override supported
capabilities of the phy. It is required when MAC cannot handle all
speeds supported by phy.

For example phy supports up-to 1Gb connections while MAC may only work
in modes up to 100 or even 10 Mbit/sec.

c74c8e6651 dm: net: Adjust PHY interface to work with CONFIG_DM_ETH
When driver model is used for Ethernet a few functions are passed a udevice
instead of an eth_device. Also add a function to find a PHY type given its
name. This will be used to decode the device tree node.

Finally, put a phy_interface field in struct eth_pdata since this is an
important part of the platform data for Ethernet.

9b18e5199e net/phy: Add support for CS4315/CS4340 PHY
Add support for Cortina CS4315/CS4340 10G PHY.
- This driver loads CS43xx firmware from NOR/NAND/SPI/SD device
  to initialize Cortina PHY.
- Cortina PHY has non-standard offset of PHY ID registers, thus
  we define own get_phy_id() to override default get_phy_id().
- To define macro CONFIG_PHY_CORTINA will enable this driver.

4fb3f0c802 net: phy.h: Make PHY autonegotiation timeout configurable
The Marvell MV78460 eval board DB-78460-BP seems to need a longer

make this timeout configurable. If not defined in the board config
header the original 4000ms is used.

9082eeac5d phylib: Add a bunch of PHY drivers from tsec
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.

5f184715ec Create PHY Lib for U-Boot
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.

Pulled ethtool.h and mdio.h from:
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6
782d640afd15af7a1faf01cfe566ca4ac511319d
With many, many deletions so as to enable compilation under u-boot
