m68knommu: Fix support for console port other than ttyS0 on mcf.c

2009-03-24T05:17:43+00:00

Due to a case of backwards logic, mfc.c always makes the console port be
ttyS0 even when you ask for another port.

This patch fixes this issue.

Only when the requested port is NOT in the range 0 to MAXPORTS-1 do we
force it to be treated as if port 0 was requested.  Forcing the port to
0 when it is in fact in the range 0 to MAXPORTS is not helpful.

Tested with working console on ttyS2 on a 5271evb.

m68knommu: fix ColdFire 5272 serial baud rates in mcf.c

2009-01-27T06:42:00+00:00

I noticed (the hard way) that the mcf.c driver doesn't support the fractional precision register on the MCF5272.  This makes the console dicey at 115200 baud and a system clock of 66.0 MHz.  On the other hand, if your hardware is running at 66.666 MHz, it probably isn't a problem.

serial: fix platform driver hotplug/coldplug

2008-04-16T02:35:40+00:00

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable serial
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...

m68knommu: new style ColdFire UART driver

2007-10-23T15:32:34+00:00

A new style serial driver for the Freescale ColdFire UART to replace
the old style one currently in the tree (drivers/serial/mcfserial.c).

Currently this UART is only found in the ColdFire CPU family of parts
(thus I prefixed this patch [M68KNOMMU]).

This has been around for a long while now, tested on all available
platforms.
