Space Qualified RTEMS

[Rolf Schroedter]

This is mainly two patches. Both are problems with the Leon port, not 
the RTEMS itself.

1. LEON startup code overwrites RTEMS system configuration under some 
circumstances:

2. RTEMS - rtems_clock_get_uptime() fails during timer tick:

Both problems have been discussed last year with Konrad Eisele, but my 
patches are still not included in the current Gaisler release.
(I checked the latest 
ftp://gaisler.com/gaisler.com/rcc/src/rtems-4.10-1.2.0-src.tar.bz2 dated 
11/2011).

AFAIK the patch for problem 2. has been included into the current RTEMS 
branch by Joel Sherrill.

@Phil: If you need these patches, I can send them to you by eMail.

Regards,
Rolf.
