Due to grown code sizes the TQM85xx boards don't build any more with
some older tool chains (like ELDK 4.2). As these boards have long
reached EOL it seems a waste of effort trying to fix them. The vendor
has agreed to drop support for them, too. So let's get rid of them.

We set sata_curr_device to 0 right after returning from init_sata(), so there's
no point in setting it to the last scanned driver at this point.
Note: there are more duplicities with cmd_sata, but those might be required,
as the code seems to reset the entire controller on every scan, ignoring the
requested port number.

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.

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.

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.

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards. We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging
constant strings in objects. Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

Add AX88772B ID together with two fixes needed to make this work.
1. The packet length check has to be adjusted, as all ASIX chips
only use 11 bits to indicate the length. AX88772B uses the other
bits to indicate unrelated things, which cause the check to fail.
This fix is based on a fix for the Linux kernel by Marek Vasut.
Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a
2. AX88772B provides several bulk endpoints. Only the first
IN/OUT endpoints work in the default configuration. So stop
enumeration after we found them to avoid overwriting the
endpoint config with a non-working one.

Initial device MAC should be read while getting info about the
device, so it's wrong to only read it in asix_init().
Add a dedicated function to read the initial MAC, which is also
able to handle devices that have their initial MAC stored in
EEPROM. Call this function inasix_eth_get_info().

The basic device reset ensures that the device is ready to
service commands and does not need to get redone before each
network operation.
Split out the basic reset from asix_init() and instead call it
from asix_eth_get_info(), so that it only gets called once.

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.

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.

Several DIU registers were being initialized either unnecessarily or to
wrong values.
1) All interrupts were enabled even though there's no interrupt handler.
Interrupts were left enabled when booting Linux.
2) Don't configure a dummy area descriptor, since we don't support ADs
in U-Boot.
3) Don't configure any write-back buffer registers, since we don't use
that mode.
4) The default values for the THRESHOLDS, SYN_POL, and PLUT registers
should be used, so don't touch those registers either.
