Hi,all,
I am planning to run linux-ppc on ppc823 FADS board.
As all know, the kernel is resided in flash rom, then upon power-on,

kernel

quoted

is copied to RAM.
I wonder if I can just put data segment to ram and leave code segment to
FLASH, just as uClinux
has done. such method will save some ram space, which makes sense on
embedded solutions.
Can you give me a hint how to realize it ?
Any suggestion is appreciated !

This method is called XIP (for execute in place) and is available on
some other architectures.  I don't know what it would take for the PPC,
but you could look at the work done on the Hitachi SH - I know it's

supported

there.

Thanks a lot !
but where can I find the work about "Hitachi SH - " ?
Is there some data accessable through www ?
Best Regards
