Why would you need fdt_addr and fdt_addr_r ? This makes no sense. Two different values would only be needed if there was NOR flash available where we could read the FDT from without loading it to RAM first. AFAIK ther ewill never be variants of the Wandboard with NOR flash, so you will always have to load the FDT to RAM first - thus the destinction makes no sense.
please go and read the cmd_pxe.c file it specifies the use of the two variables. one is for a system provided dtb and the other is for a user provided dtb
But this is crap. The meaning of these variables has been wel-defined for a long, long time. "fdt_addr" is the FDT address in NOR flash (or similar memory except system RAM); "fdt_addr_r" is the FDT address when loaded to system RAM (hence the "_r" in the variable name).
Arbitariry redefining this meaning is counterproductive and confusing.
If cmd_pxe.c uses incorrect names, then please fix the bug there.
Best regards,
