upper layers, namely line discipline, need to be notified
when transmission of more data is possible. For spurious
cases, where IRQ handling does not supply notification
for sure, it is given additionally here, when data has just
been transmitted and space in the buffer will most probably
be available.

"have_rtscts" is assigned 1, while it is declared
int:1, two's complement, which can hold 0 and -1
only. The code works, as the upper bits are cut
off, and tests are done against 0 only.
Nonetheless, correctly declaring the bit field
as unsigned int:1 renders the code more robust.

The UART RX handling code isn't exactly speeding, so don't go disabling

Add some comments for how these anomalies are addressed:
05000215 - UART TX Interrupt Masked Erroneously
We always clear ETBEI within last UART TX interrupt to end
a string. It is always set when starting a new tx transfer.
05000099 - UART Line Status Register (UART_LSR) Bits Are Not Updated at
the Same Time
This anomaly affects driver only in POLL code where multi bits of
UART_LSR are checked. It doesn't affect current bfin_5xx.c driver.

This bug is caused by irregular behavior of DMA register CURR_X_COUNT
and CURR_Y_COUNT when an auto restart uart rx DMA run to last byte in
DMA buffer, trigger the interrupt and stay at this possiton. The status
of current x and y is 0:7 instead of 512:8 or 0:8. The driver doesn't
take care of this case when calculating the position.

Since we already setup the early console UART in
arch/blackfin/kernel/early_printk.c, and common functions which are
enabled from the .setup will override the proper settings later, don't
fill in these structures. Otherwise we get mangled baudrate settings when
using early_printk.

SPORT transmit frame sync (TFS) isn't used as an electrical signal during
normal SPORT UART emulation. However, it is useful in EIA RS-485
emulation as RS-485 Transceiver Driver Enable DE strobe.
This patch configures:
TFS to be active high in order to drive an DE strobe of
an eventually connected RS-485 Transceiver.
Late frame sync mode (LATFS) gating the entire TX shift cycle.

I found the PrimeCell/AMBA Bus drivers distrusting the resource
passed in as part of the struct amba_device abstraction. This
patch removes all hard coded resource sizes found in the PrimeCell
drivers and move the responsibility of this definition back to
the platform/board device definition, which already exist and
appear to be correct for all in-tree users of these drivers.
We do this using the resource_size() inline function which was
also replicated in the only driver using the resource size, so
that has been changed too. The KMI_SIZE was left in kmi.h in case
someone likes it. Test-compiled against Versatile and Integrator
defconfigs, seems to work but I don't posess these boards and
cannot test them.

If you setserial a port which has never been initialised we change the type
but don't update the I/O method pointers. The same problem is true if you
change the io type of a port - but nobody ever does that so nobody noticed!
Remember the old type and when attaching if the type has changed reload the
port accessor pointers. We can't do it blindly as some 8250 drivers load custom
accessors and we must not stomp those.

The second argument of the probe method points to the amba_id
structure, so it's better passed with the correct type. None of the
current in-tree drivers uses the pointer, so they have only been
checked for a clean compile.
