-To do:
-- software impact of not having NOR on Qi and kernel
+Software impact: Qi must pass an "mtdparts=" parameter without the
+"physmap-flash" entry and the kernel must not register a NOR device
+On the Linux side, the absence of NOR means that the MTD device numbers

+u-boot), the partition layout changes anyway, and only a single Qi
+partition is needed for now. (Later, "factory" data may be stored as
