Okay, I'll test this, thanks!
They both needed to be passed to mkimage because they both get
checksummed individually, but stored in the same header.

Alignment and padding shouldn't be an issue here.
mkimage handles everything and spits out a complete file.

I haven't yet confirmed if the rk33 spi padding issue applies to the
rk35 series, mostly because I haven't yet achieved stable support for
