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,

Wolfgang Denk
