Dear Reinhard Meyer,

If this is really for all AT91 SoCs, then please feel free to introduce a common define (CONFIG_SYS_AT91 ?) and use that. Eventually you can clean up some other such #if's on the way.
That would have to be set either in each board.h file or in each at91*.h file.
Isn't there a central place?
Probably there is a header file common to all AT91 SoCs when then can use a single such construct to #define the new variable so you don;t have to touch all the many board config files.
The only files I can see included in each instance are those of the kind hardware.h, memory_map.h and similiar. The define does not really belong in any of those.
If no better place is found, we can even add this to <common.h> (we do similar things there already for CONFIG_MPC866_FAMILY, CONFIG_MPC86x, CONFIG_MPC8272_FAMILY, CONFIG_TQM8xxM, CONFIG_TQM8xxL, etc.
Q: after relocation, "gd->" values are still available, right?
Yes, it gets relocated to RAM, too, and then remains available.
I am searching for further "violations"...
Good luck!
Best regards,
Wolfgang Denk
