Make sure to keep the MAC address programmed in the SMC911x ADDRH
and ADDRL registers. Linux can read those registers to determine
the MAC address on EEPROM-less configurations.

The include/miiphy.h header duplicates a lot of things from linux/mii.h.
So punt all the things that overlap to keep the API simple and to make
merging between U-Boot and Linux simpler.

SMSC911x chips have alignment function to allow frame payload data
(which comes after 14-bytes ethernet header) to be aligned at some
boundary when reading it from fifo (usually - 4 bytes boundary).
This is done by inserting fake zeros bytes BEFORE actual frame data when
reading from SMSC's fifo.
This function controlled by RX_CFG register. There are bits that
represents amount of fake bytes to be inserted.
Linux uses alignment of 4 bytes. Ethernet frame header is 14 bytes long,
so we need to add 2 fake bytes to get payload data aligned at 4-bytes
boundary.
Linux driver does this by adding IP_ALIGNMENT constant (defined at
skb.h) when calculating fifo data length. All network subsystem of Linux
uses this constant too when calculating different offsets.
But u-boot does not use any packet data alignment, so we don't need to
add anything when calculating fifo data length.
Moreover, driver zeros the RX_CFG register just one line up, so chip
does not insert any fake data at the beginig. So calculated data length
is always bigger by 1 word.
It seems that at almost every packet read we get an underflow condition
at fifo and possible corruption of data. Especially at continuous
transfers, such as tftp.
Just after removing this magic addition, I've got tftp transfer speed as
it aught to be at 100Mbps. It was really slow before.
It seems that fifo underflow occurs only when using byte packing on
32-bit blackfin bus (may be because of very small delay between reads).

This patch turns off MAC address mismatch warning when
optional eeprom programmed with MAC address is not available.
In that case, smc911x's MAC address register has its default
value ff:ff:ff:ff:ff:ff and it's not a valid address. This
makes eth_initialize() show the warning which has no
meaningful information while environment variable ethaddr
overrides the address read from the register. If there's no
eeprom and the value of MAC address register is not valid
after initialization, dev->enetaddr had better not be updated
and maintain its initial value 00:00:00:00:00:00, which I
think is what eth_initialize() expects. This is not a bug fix.
Even without this patch, the driver works fine. It's just for
enhancing the way of displaying messages.

Refactor the smc911x driver to allow for detecting when the chip is missing.
I.e. the detect_chip() function is called earlier and will abort gracefully
when the Chip ID read returns all 1's.

This reverts commit ca9c8a1e10fac01e6a1129f82a7ce18bd818fa43,
which causes compile warnings ("large integer implicitly truncated
to unsigned type") on all systems that use this driver. The warning
results from passing long constants (TX_CFG, RX_CFG) into
smc911x_set_mac_csr() which is declared to accept "unsigned
character" arguments only.
Being close to a release, with nobody available to actually test the
code or the suggested fixes, it seems better to revert the patch.

eth_halt() function in the smc911x drivers used to call the
smc911x_reset() function. eth_halt() used to be called after
tftp transfers. This used to put the ethernet chip in reset
while the linux boots up resulting in the ethernet driver
not coming up. NFS boot used to fail as a result.
This patch calls smc911x_shutdown() instead of smc911x_reset().
Some comments received has also been fixed.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
Also, do not bother checking the EEPROM if the env is setup. This
simplifies the code greatly.

The smc911x driver has a lot of useful defines/functions which can be used
by pieces of code (such as example eeprom programmers). Rather than
forcing each place to duplicate these defines/functions, split them out
of the smdc911x driver into a local header.

The RSK7203 board has the SMSC9118 wired up 'incorrectly'.
Byte-swapping is necessary, and so poor performance is inevitable.
This problem cannot evade by the swap function of CHIP, this can
evade by software Byte-swapping.
And this has problem by FIFO access only. pkt_data_pull/pkt_data_push
functions necessary to solve this problem.

When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.
The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).
