607c268ef9 serial: bfin_5xx: fix building as module when early printk is enabled
Since early printk only makes sense/works when the serial driver is built
into the kernel, disable the option for this driver when it is going to be
built as a module.  Otherwise we get build failures due to the ifdef
handling.

9c529a3d76 serial: bfin_5xx: add missing spin_lock init
The Blackfin serial driver never initialized the spin_lock that is part of
the serial core structure, but we never noticed because spin_lock's are
rarely enabled on UP systems.  Yeah lockdep and friends.

2860b79111 Blackfin Serial Driver: disable dma rx interrupt only rather than all irqs
The UART RX handling code isn't exactly speeding, so don't go disabling
all interrupts when processing the buffer.  Just disable the relevant DMA
interrupt.  This greatly improves latency of the system when utilizing the
UART.

84507794a9 Blackfin Serial Driver: handle anomaly 05000231
05000231 - UART STB Bit Incorrectly Affects Receiver Setting
For processors affected by this, we cannot safely allow CSTOPB to be set
as the UART will then be unable to properly clock in bytes.

0efa4f2c94 Blackfin Serial Driver: annotate anomalies 05000215 and 05000099
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.

35ff693579 Blackfin Serial Driver: handle irregular DMA register status in auto start mode
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

fill in these structures.  Otherwise we get mangled baudrate settings when

80d5c474b8 Blackfin Serial Driver: fix bug - SIR driver stop receiving randomly
Bug description:
The IRDA receiver may can't receiving any more after processed some signals.

To duplicate this issue is put three IRDA devices together, one blackfin,
two none blackfin, they will detect each other. Let one none blackfin devices
irdaping the blackfin devices, when it stopped print out ping information,
it is the time that blackfin stoped receiving, the time is random.

The related register bit is OK, the other devices is sending data continuously.
But no interrupt come.

Fixing:
I tried Michael's suggestion that request the UARTx error interrupt, and reset
the IRDA when found FE error. This method helps much, but it can't completely
avoid stop.

Reset the IRDA before every time sending the data is more safe.

platform drivers, to re-enable auto loading.

NOTE that Kconfig for some of these drivers doesn't allow modular builds, and
thus doesn't match the driver source's unload support.  Presumably their
unload code is buggy and/or weakly tested...
