For the record; this patch was lifted from my dev tree and in turn I stole it from Scott Wood. > > > +$(obj)/zImage.raw: vmlinux $(dts) $(wrapperbits) > > + $(call if_changed,wrap,raw,$(dts)) > > > > This should be handled by the standard zImage% rule. It's weird. On my system the standard zImage rule wouldn't do this target. I had to add this rule just to get it to compile. I've not yet been motivated to revisit and fix it. > I'm not sure exactly what platform you are using this on.

Heh; actually it's a platform with *no* firmware. :-) It's on a Xilinx FPGA. SDRAM is initialized by the FPGA design and the kernel image is loaded either with a debugger, or via the SystemACE device. In either case, the kernel is the first thing to run after reset.... oh, and reset is not as complete as one would normally expect. Cheers, g. -- Grant Likely, B.Sc., P.Eng.
