Yeah, I saw that, and am planning on taking it ASAP, so still this
release. However I wanted to have this tested, which is now easier since I
got my LicheePi Nano on Friday. So SPI boot seems to work, but I needed to
fix FEL boot in mainline (see the other patch).

I am not convinced with the uint32_t part, though. I think "int" is fine,
because it's either -1 or the uint8_t returned by readb(), which fits both
nicely and correctly into an "int".

I will do some more testing and then see what other patches I can pick up
(Jernej's PRCM ones, for instance).

Cheers,
Andre
