dtc: Enable and fix -Wpointer-arith warnings
This patch turns on the -Wpointer-arith option in the dtc Makefile, and fixes the resulting warnings due to using (void *) in pointer arithmetic. While convenient, pointer arithmetic on void * is not portable, so it's better that we avoid it, particularly in libfdt. Also add necessary definition of uintptr_t needed by David Gibson's changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition comes from stdint.h, which u-boot doesn't have). -- gvb Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
