Using onchip RAM in iMX28

Hi,

 

Does anyone know of have an example of placing Linux kernel code in the onchip RAM on i.MX28?

 

I can see a mapping for the area is setup in mm-mx28.c, but I don't think there's anything done to support linking/loading code to that area.

 

Particularly I'd like to put fec.c:swap_buffer() into the onchip RAM and see if my networking can get a bit faster (I look to be CPU limited at about 65MBit/s).

 

Kind Regards,

Mike
