[linuxsh-dev] ST40STB1 changes

[Stuart M. <Stu...@st...>]

Folks

I've just checked in a bundle of changes which add support for the
ST40STB1 (which is the first SH4 variant from STMicroelectronics) and
the corrisponding boards (HARP and Overdrive).

Most of the changes are simply adding STB1 where there is a list of
devices, and new board/chip specific files, but there are a few other
changes which you may (hopefully not) need to be aware of:

 - I've added a 'shift' parameter to the HD64465 I/O address mapping
   functions.  This was needed to allow the standard 16550 serial
   driver to work with the serial port on the HD64465.

 - I fixed what appears to be be a problem in the RTC handling of
   1/128 second register.

 - In the SCI code I've moved the interrupt installation code from when
   the driver is initialised to when it is opened for the first time. This
   allows the SCI to be used by another driver when not needed for a TTY.

 - A reworking of the way NR_IRQ is calculated to make it easier to expand.

A more complete list of changes is in the ChangeLog.

Hopefully I've not broken anything, but please let me know if you have
any problems.
