67449098a8 FEC: Rework the TX wait mechanism
The mechanism waiting for transmission to finish in fec_send() now
relies on the E-bit being cleared in the TX buffer descriptor. In
case of data cache being on, this means invalidation of data cache
above this TX buffer descriptor on each test for the E-bit being
cleared.

Apparently, there is another way to check if the transmission did
complete. This is by checking the TDAR bit in the X_DES_ACTIVE
register. Reading a register does not need any data cache invalidation,
which is beneficial.

Rework the sequence that wait for completion of the transmission so that
the TDAR bit is tested first and afterwards check the E-bit being clear.
This cuts down the number of cache invalidation calls to one.

e2a66e6097 FEC: Do not pass unaligned buffer to network stack
Do not pass unaligned RX buffer to the upper layers. The upper layer,
especially in the ARP case, recycles the buffer and passes it back into
the FEC, into it's TX path. With caches enabled, the FEC hangs on this
from time to time.

b737337aaf net/phy: support the mv88e6352 switch
This patch add support for the configuration of an external switch from
the 88E6xxx series from Marvell trough an MDIO link using indirect
adressing. This can be used if we do not want to use an EEPROM for the
configuration.

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.

f8be7d659c net: Improve the speed of netconsole
Previously u-boot would initialize the network interface for every
network operation and then shut it down again.  This makes sense for
most operations where the network in not known to be needed soon after
the operation is complete.  In the case of netconsole, it will use the
network for every interaction with the shell or every printf.  This
means that the network is being reinitialized very often.  On many
devices, this intialization is very slow.

This patch checks for consecutive netconsole actions and leaves the
ethernet hardware initialized between them.  It will still behave the
same old way for all other network operations and any time another
network operation happens between netconsole operations.

7f51898c1b net: Make netconsole src and dest ports configurable
It is desirable to use different port numbers for sending and receiving
packets with netconsole in the case where you have more than one device
on the local subnet with netconsole enabled for broadcast.  When they
use the same port for both, any output from one will look like input to
the other.  This is typlically not desirable.

This patch allows the input and output ports to be specified separately
in the environment.

At the moment, the driver supports the following CPUs:
 - GETHER (Gigabit Ethernet) : SH7763, SH7734
 - ETHER  (Fast Ethernet)    : SH7724, SH7757

And the driver had the following "#if":

 #if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734)
 #if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724)
 - Those are for GETHER

 #if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757)
 - This is for ETHER

SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if".

9d2d924a0a net: fec_mxc: Fix setting of RCR for xMII
At least on i.MX25, the RMII mode did not work, which is fixed by this patch.

The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.

According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

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.

ece223b52a net: Refactor to separate the UDP handler from the ARP handler
Call a built-in dummy if none is registered... don't require
protocols to register a handler (eliminating dummies)
NetConsole now uses the ARP handler when waiting on arp
(instead of needing a #define hack in arp.c)
Clear handlers at the end of net loop

594c26f8a7 net: cosmetic: Un-typedef IP_t
Rename IP header related things to IP_UDP. The existing definition
of IP_t includes UDP header, so name it to accurately describe the
structure.

10cbe3b6a4 net: Fix remaining API interface breakage
These are all the files which use the API incorrectly but did not get
built using MAKEALL -a powerpc|arm.  I have no compiler for them, but
the remaining issues should be far less than without this patch.

Any outstanding issues are left to the maintainers of boards that use
these drivers.
