Unfortunately I had to drop this as it caused warnings when building:

lib/fdtdec.c: In function ‘fdtdec_get_addr_size_auto_noparent’:
include/fdtdec.h:27:25: warning: large integer implicitly truncated to
unsigned type [-Woverflow]
 #define FDT_ADDR_T_NONE (-1ULL)

Would you please take a look? Also can you add a MAINTAINER file for
sandbox/sandbox64?

Sorry for the late notice.

Thanks,
Simon
