ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI
specification suggests) which leads to the controller seeing the "token" field
as the previous call has left it, i.e.:
- if a timeout occured on the previous call (Active bit left as 1), controller
incorrectly tries to complete a previous transaction on a newly programmed
endpoint;
- if a halt occured on the previous call (Halted bit set to 1), controller just
ignores the newly programmed TD(s) and the function then keeps returning error
ad infinitum.
This turned out to be caused by the wrong orger of the arguments to the memset()
call in ehci_alloc(), so the allocated TDs weren't cleared either.
While at it, stop needlessly initializing the alternate next TD pointer in the
QH transfer overlay...

The following restructuring and optimisations increase the SPI
read performance from 1.3MiB/s (on da850) to 2.87MiB/s (on da830):
Remove continual revaluation of driver state from the core of the
copy loop. State can not change during the copy loop, so it is
possible to move these evaluations to before the copy loop.
Cost is more code space as loop variants are required for each set
of possible configurations. The loops are simpler however, so the
extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX
defined.
Unrolling the first copy loop iteration allows the TX buffer to be
pre-loaded reducing SPI clock starvation.
Unrolling the last copy loop iteration removes testing for the
final loop iteration every time round the loop.
Using the RX buffer empty flag as a transfer throttle allows the
assumption that it is always safe to write to the TX buffer, so
polling of TX buffer full flag can be removed.

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).
