Hi Grzegorz,

Long time ago I was add to my todo list item to add FDT support to
geom_map module. Now you have good replacement.
(/me cut off one item from todo)

Just one question:
it is possible to not assume that parent media is NAND?

+		if (g_io_getattr("NAND::device", cp, &size, &dev))
+			break;
