No, TRAB is not a PXA system. It's a s3c2400 board.

No, this is not correct.

The only effect of this is to put the  environment  into  a  separate
linker  section. You can do this, but you don't have to. You can make
this work without this setting es well. Just  configure  your  linker
script correctly.

This is an error in your linker script then.
