3177457853 net/phy: Fix the phy id mask of AR8031
The both AR8031 and AR8035 belong to Atheros 803x serial PHY.
So the phy id mask of AR8031 is the same to the phy id mask
of AR8035. The right mask value is 0x4fffff.

This patch has been tested on the P1010 and P1023.

4220504767 net/phy: realtek: Fix the PHY ID mask to ensure the correct Realtek PHY is detected
The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following
method to determine which driver is to be loaded for a particular PHY
module:

list_for_each(entry, &phy_drivers) {
	drv = list_entry(entry, struct phy_driver, list);
	if ((drv->uid & drv->mask) == (phy_id & drv->mask))
		return drv;
}

This means that a drv->mask of 0xfffff0 will return incorrect phy driver
for the logic above, even if the drv->uid is anything other than
something ending with a 0x0.

For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff
and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then
the phy driver selected will always be RTL8211B even though the
underlying phy connected on the board is a 8211E module.

This patch fixes this issue.

9ba30f6bc2 phy: fix 10/100Mbps operation on 1Gbps-capable links
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.

This driver is not generic and was not tested on other switches than the
88e6352. This is proposed as a first implementation that is somewhat
limited but works and that can be used as a basis for further
developments for this switch family.

2339e4972f phylib: wait for TN2020 to achieve SERDES lane alignment at startup
Before the Teranetics TN2020 PHY can be used, the SERDES lanes need to be
aligned, so wait for lane alignment before completing the startup sequence.

Note that this process can take up to three seconds.

ebfdacb42b phylib: Work around bug in Teranetics PHY
The Teranetics PHY does not properly report the link state
for fiber connections. The new PHY code actually checked the link,
and so the FM driver would refuse to talk over a linkless PHY.

But the link may actually be up, so now we always report it as up
for fiber connections on the tn2020.

0dcfb0fcb8 Revert "phylib: remove a couple of redundant code lines"
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.

ee8fa20f54 phylib: Detect link on 10G devices correctly
gen10g_startup() had 2 bugs:

1) It had a boolean logic error in checking the MMD mask, and
always checked all of them.

2) It checked devices which don't actually report link state, which
meant that it would never believe the link was fully up.

Fix the boolean logic, and then mask the MMD mask so only link-reporting
devices are checked.

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

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

4ba31ab33a Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.
This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII       - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT      - Generic code to enable the MII bus (optional)
MDIO_DECLARE  - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE   - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ     - Read the MDIO pin
MDIO(v)       - Write v on the MDIO pin
MDC_DECLARE   - Declaration needed to access to the MDC pin (optional)
MDC(v)        - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[]            - The symbolic name that must be equal to the MII bus
                         registered name
int (*init)()          - Initialization function called at startup time (just
                         before the Ethernet initialization)
int (*mdio_active)()   - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)()      - Write the MDIO pin
int (*get_mdio)()      - Read the MDIO pin
int (*set_mdc)()       - Write the MDC pin
int (*delay)()         - Delay function
void *priv             - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
 { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
 { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
 ...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
                          sizeof(bb_miiphy_buses[0]);
