rtems_clock_set @ sparc v7 does not work!

[Grigori Khmyrov]

Yes, it would be reasonable explanation!
I use RTEMS 4.0.0 for the sparc BSP
And 4.6.2 for i386 BSP (which works)

How can I patch "memory barrier" for version 4.0.0?
I can not switch easy to the new rtems version because of mkprom support.

Thank you,
Grigori
