Approved by: re (implicit) This commit was manufactured to restore the state of the 6.4-RELEASE image.

Partial MFC of rev 1.22 (the other bits were already MFC'd by marcel).

Additionally, remove the probe for the high 4 bits of IER being 0 and don't assume we can always read/write 0 to/from those bits. This is needed to get uart(4) to work on Xscale PXA255 and IXP425.

Partial MFC: Remove 16-bit wide I/O. It breaks when the register shift

is non-null and may not work on all chipsets. PR: i386/105616 Tested by: Helge Oldach

Include the common instead of the private

. The latter can be removed now.

Be slightly more paranoid about using the divisor in a division and

the calculated baudrate. Neither should be 0.

Implement UART_IOCTL_BAUD. Consequently, when the baudrate was unset

for the console, we emit the actual baudrate during bus enumeration.

Do not use hardware flow control for the moment. There are some issues

with it that need to be understood better before they can be resolved. This takes time and time is already in short supply. Reported & tested by: glebius@

When sizing the FIFO, don't count all the way up to 1030 if any FIFO

2004-07-26T03:54:40Z

size larger than 128 is considered an incompatible size. Stop counting when we reach 130 in the loop.

Use the new serial port definitions for modemsignals.
