DENX Software Engineering proudly announce:

On our FTP server you can find our first public  release  of  patches
that  allow the use of the Linux Real-Time extensions RTAI (Real-Time
Application Interface,  Version  RTAI-24.1.4)  and  RTLinux  (Version
RTLinux-3.0)  on  the  Embedded  PowerPC  Controllers of the Motorola
MPC8xx family. The patches are running and have been tested with  the
Linux  version  2.4.4  kernel,  which  is  avaliable  on the same FTP
server.

Rationale: Both real-time extensions of the Linux  kernel  (RTAI  and
RTLinux) have been running on the PowerPC architecture for some time.
But  so  far they only supported the "bigger" CPU's. They did not run
on Embedded Controllers like the Motorola PowerQICC CPU's, which  are
very  attractive  for  embedded systems since they integrate a lot of
peripheral functions which allows for very  small  systems  like  the
half-credit-card sized TQM8xxL mini-modules. With our patches you can
run Linux applications with hard real-time requirements on such small
systems.

There are also several new features in our version of the Linux 2.4.4
kernel, like a framebuffer driver to control LCD displays on a MPC823
processor, or a new version of the MPC8xx UART driver  that  supports
hardware flow control on all 4 SCC ports.
