That's the equivalent of saying Linux doesn't support something because
nobody bothered to enable it in a certain defconfig.

I'm not sure what SPI and SD have to do with it...
Most of the latter patch is concerned with NAND boot, which is a
different issue from NAND support, but still pretty important if you're
going NAND-only. It looks like the patches were actually initially
separate, but Kumar oh-so-helpfully squashed them together.
One thing I would like to see fixed in at upstream version of p1022ds
NAND boot support is for it to use SPD like a normal p1022ds boot. This
will likely require reviving the three-stage boot discussion (TPL).
