early_serial_setup
Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.
The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.

Fit blackfin uart over sport driver into common uart inftrastructure. It
is based on the early platform interfaces to get the platform data early
when the console is initilized.
1. Enable sport uart driver to change uart baud, data bit, stop bit at
runtime. Bind the index of uart device nodes to physical index of
sports.
2. Move all platform data into arch specific board files. Register
and probe platform device data in both early and normal stages.
3. Console is registered in sport uart driver as well.
4. Remove 500 us block waiting in sport tx stop code by putting a
dummy data into tx fifo to make sure the sport tx stops when all bytes
are shifted out except for the dummy data.
5. clean up a bit and fix up coding style.

Limit the amount of address space claimed for Alchemy serial ports to
0x1000. On the Au1300, ports are only 0x1000 apart, and the registers
only extend to 0x110 at most on all supported alchemy models.
On the Au1300 the autodetect logic no longer works and this makes it
necessary to specify the port type through platform data. Because of
this the MSR quirk needs to be moved outside the autoconfig() function
which will no longer be called when UPF_FIXED_TYPE is specified.

When controlling an industrial radio modem it can be necessary to
manipulate the handshake lines in order to control the radio modem's
transmitter, from userspace.
The transmitter should not be turned off before all characters have been
transmitted. serial8250_tx_empty() was reporting that all characters were
transmitted before they actually were.
===
Discovered in parallel with more testing and analysis by Kees Schoenmakers
as follows:
I ran into an NetMos 9835 serial pci board which behaves a little
different than the standard. This type of expansion board is very common.
"Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together
with the "UART_LSR_THRE" bit when writing data to the device.
The NetMos device does it slightly different
I believe that the TEMT bit is coupled to the shift register. The problem
is that after writing data to the device and very quickly after that one
does call serial8250_tx_empty, it returns the wrong information.
My patch makes the test more robust (and solves the problem) and it does
not affect the already correct devices.
Alan:
We may yet need to quirk this but now we know which chips we have a
way to do that should we find this breaks some other 8250 clone with
dodgy THRE.

Perform a tricky suspend/resume even with no_console_suspend.
With no_console_suspend, kernel skips serial port suspend/resume and the
serial hardware may remain in undefined state after resume. It actually
happens on devices that don't have BIOS that handle serial
initialization. It makes impossible to use serial console after resume.
Devices affected by this problem include:
Sharp Zaurus devices
Several PXA based ARM embedded boards
The patch does:
- Save the hardware state
- Perform buffer flush in time of its suspend call
- Tell the driver that port is suspended
- But still accept new data
- And keep console hardware in state that allows to send them
It allows to capture late console messages without breaking console
after resume.
This is just a resend of a patch discussed in these threads, as the
patch was not yet applied.

It seems that in qemu, we can see an interrupt in R3 despite the
fact that it's masked in W1. The chip doesn't actually issue an
interrupt, but we can "see" it when taking an interrupt for the
other channel. This may be a qemu bug ... or not, so let's be
safe and avoid calling into the UART layer when that happens which
woulc cause a crash.

The sh-sci driver used the wrong fifosize for PORT_SCIFA and PORT_SCIF
ports. If an incorrect size is used, the serial core will enforce an
early shutdown on the port, especially with baudrates < 9600.

ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard

remaining sh-sci straggles over, which enables the driver to be wired up

Several IOC3 and IOC4 drivers misuse the __devinit and __devexit section
markers. Use __init and __exit instead as appropriate, then add __devinit
and __devexit where they really belong for PCI drivers.
Also make ioc4_serial_init static.

This is V2 of early serial console support for the sh-sci
driver. The early serial console is using early platform
devices and "earlyprintk". To use this feature the early
platform devices must be broken out to one device per port
and the desired port should be selected on the kernel command
line like: "earlyprintk=sh-sci.N[,baudrate][,keep]"

Do not read IIR in serial8250_start_tx when UART_BUG_TXEN
Reading the IIR clears some oustanding interrupts so it is not safe.
Instead, simply transmit immediately if the buffer is empty without

Intel(R) PXA27x Processor Family Specification Update (Nov 2005)
says:
E75. UART: Baud rate may not be programmed correctly on
back-to-back writes.
Problem:
When programming the Divisor Latch registers, Low and High (DLL and
DLH), with back-to-back writes, the second register write may not
take effect. The result is an incorrect baud rate.
Workaround:
After programming the first Divisor Latch register, read and verify
it before programming the second Divisor Latch register.
This was hit when changing the baud rate from 115200 to 9600 while
receiving characters at 9600 Bd.
And fixed indention of some comments nearby.
