The Amlogic Meson GXL/GXM families embeds an internal RMII Ethernet PHY.
The PHY acts as a generic PHY but needs a slight configuration right
before it's configuration.

All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.
The underlying drivers should be responsible for the cache operation.
Remove these codes completely.

The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. With this patch we enable the TX delay for
PHY_INTERFACE_MODE_RGMII_ID and PHY_INTERFACE_MODE_RGMII_TXID and
disable it for PHY_INTERFACE_MODE_RGMII.
Based on a similar change made in the Linux Realtek PHY driver
by Martin Blumenstingl <[email protected]>.

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they
share the same ID. Drivers for bothe PHYs cannot safely coexist, so
the solution was to use #ifdefs to select between the two drivers.
As a result KSZ9031, which has a unique ID, is now caught in the
crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031
will not function properly, as some essential configuration code is
ifdef'd-out.
To prevent such situations, move the KSZ9000 drivers to a separate
file, and place them under a separate Kconfig option. While it is
possible to enable both KSZ8000 and KSZ9000 drivers at the same time,
the assumption is that it is highly unlikely for a system to contain
both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers
will be enabled at any given time.

Commit a058052c changed the generic phy_reset() to clear all bits in
BMCR. This inevitably clears the ANEG bit. m88e1145 requires any
change to ANEG bit to be followed by a software reset. This seems to
be different from other PHYs. Implement read-modify-write procedure
for this PHY init.

The 88E1518 code is programming the wrong registers for rgmii-id,
rgmii-txid and rgmii-rxid interfaces.
Since the PHY defaults to rgmii-id, it would appear that the code
was previously only used with sgmii and rgmii-id interfaces.
Tested on 88E1512 PHY in rgmii-id mode which is from the same family
as 88E1518.

This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).
For this purpose we introduce a new phy-driver, called "Fixed PHY".
Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.
Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).
During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

The VSC8601 config tried to add an RGMII skew based on #defines that
no config defines. That's quite an ugly way to do it. Since the skew

Commit 525d187af ("net: phy: Optionally force master mode for RTL PHY")
added the define to force the PHY into master mode. Unfortunatly this is
an all or nothing switch. So it applies to either all PHY's or no PHY's.
The bug that define tried to solve was a buggy PLL in the RTL8211C only.
The Olimex OLinuXino Lime2 has gotten an upgrade where the PHY was
replaced with an RTL8211E. With this define however, both lime2 boards
are either forced to master mode or not. We could of course have a
binary for each board, but the following patch fixes this by adding a
'quirk' to the flags to the rtl8211b and rtl8211c only. It is now
possible to force master mode, but only have it apply to the rtl8211b
and rtl8211c.

The Marvell Link Street mv88e60xx is a series of FastEthernet switch
chips, some of which also support Gigabit ports. It is similar to the
mv88e61xx series which support Gigabit on all ports.
The main difference is the number of ports. Which affects the
PORT_COUNT define and the size of the mask passed to
mv88e61xx_port_set_vlan().
Other than that it's just a matter of adding the appropriate chip
IDs.
