I just got back from vacation, but the patches look reasonable.

I'd leave out the space before the colon ("foo: bar", not "foo : bar"),
though.  I think that may be a regional style issue, but let's stick with
what the rest of the code does.

[U-Boot] [PATCH 1/2] NAND: show manufacturer and device ID for unknown chips

[Florian Fainelli]

When the NAND part is not supported, it is useful to show the manufacturer
and device ID to help debugging and reporting.
