Basic porting of RTEMS on flash chip for i386 board

I have once got the pc386 BSP running out of flash (on a AMD 
Elan520 CPU). There was one thing I had to change, if I have 
it in mind correctly it was an interrupt descriptor that was 
placed in the code section (flash) instead of data section 
(initialized RAM). If you want details, I can check this up.

The Elan520 board I used (from Forth Systems) had a special 
JTAG utilitiy to program the flash device.
