a1ca92eaaf dm: eth: Avoid blocking on packet reception
Some devices can take a long time to work out whether they have a new packet
or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do
this, since it waits until it gets a new packet on the wire before allowing
the USB bulk read packet to be submitted.

At present with driver mode the Ethernet receive code reads 32 packets. This
can take a very long time if we must wait for all 32 packets. The old code
(before driver model) worked by reading a single set of packets from the USB
device, then processing all the packets with in. It would be nice to use
the same behaviour with driver model.

Add a flag to the receive method which indicates that the driver should try
to find a packet if available, by consulting the hardware. When the flag is
not set, it should just return any packet data it has already received. If
there is none, it should return -EAGAIN so that the loop will terminate.

When the ethaddr changes in the env, the hardware should also be updated
so that MAC filtering will work properly without resetting U-Boot.

Also remove the manual calls to set the hwaddr that was included in a
few drivers as a result of the framework not doing it.

64dcd25f55 dm: net: Tidy up designware driver ready for driver model
Adjust the error handling to use errno.h instead of returning -1. Change
leaf functions to pass in the arguments they require rather than struct
eth_device. Apart from simplifying the code it makes is easier to reuse
these functions for driver model, since mostly they actually only use
struct dw_eth_priv (which we can keep).

Create a stub for each Ethernet operation function. This will allow use to
share code with the driver model versions.

92a190aaab net/designware - switch driver to phylib usage
With this change driver will benefit from existing phylib and thus
custom phy functionality implemented in the driver will go away:
 * Instantiation of the driver is now much shorter - 2 parameters
instead of 4.
 * Simplified phy management/functoinality in driver is replaced with
rich functionality of phylib.
 * Support of custom phy initialization is now done with existing
"board_phy_config".

Note that after this change some previously used config options
(driver-specific PHY configuration) will be obsolete and they are simply
substituted with similar options of phylib.

For example:
 * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
by default.
 * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
automatically the first discovered on MDIO bus phy will be used

I believe there's no need now in "doc/README.designware_eth" because
user only needs to instantiate the driver with "designware_initialize"
whose prototype exists in "include/netdev.h".

74cb708d58 net/designware: add explicit reset of {tx|rx}_currdescnum
Driver "init" function might be called multiple times.
On every "init" Tx/Rx buffer descriptors are initialized: "descs_init"
-> "{tx|rx}_descs_init".

In its turn those init functions set MAC's "{tx|rx}desclistaddr" to
point on the first buffer descriptor in the list.

So CPU to start operation from the first buffer descriptor as well after
every "init" we have to reset "{tx|rx}_currdescnum".

This commit is an add-on to f6c4191f. There are a few registers where
consecutive writes to the same location should be avoided or have a delay.

According to Synopsys, here is a list of the registers and bit(s) where
consecutive writes should be avoided or a delay is required:

DMA Registers:
Register 0        Bit 7
Register 6        All bits except for 24, 16-13, 2-1.

GMAC Registers:
Registers 0-3     All bits
Registers 6-7     All bits
Register 10       All bits
Register 11       All bits except for 5-6.
Registers 16-47   All bits
Register 48       All bits except for 18-16, 14.

ef76025a99 net: Multiple updates/enhancements to designware.c
This patch adds the following changes to designware ethernet driver
found on the ST SPEAr SoC:

- Don't init MAC & PHY upon startup. This causes a delay, waiting for
  the auto negotiation to complete. And we don't want this delay to
  always happen. Especially not on platforms where ethernet is not
  used at all (e.g. booting via flash).
  Instead postpone the MAC / PHY configuration to the stage, where
  ethernet is first used.
- Add possibility for board specific PHY init code. This is needed
  for example on the X600 board, where the Vitesse PHY needs to be
  configured for GMII mode.
  This board specific PHY init is done via the function
  designware_board_phy_init(). And this driver now adds a weak default
  which can be overridden by board code.
- Use common functions miiphy_speed() & miiphy_duplex() to read
  link status from PHY.
- Print status and progress of auto negotiation.
- Print link status (speed, dupex) upon first usage.
