I've managed to construct .config files (for ppc64) that come across
this Kconfig warning:

  warning: (MPC836x_RDK && MTD_NAND_FSL_ELBC && MTD_NAND_FSL_UPM)
selects
FSL_LBC which has unmet direct dependencies (FSL_SOC)

Let's add the FSL_SOC dependency to the NAND drivers. AFAICT, they are
only supported on PPC32 FSL SoCs anyway.

There are other problems, if you can enable an 83xx board on ppc64. 
 PPC_83xx
does select FSL_SOC so I don't know why it's unmet.

I don't have an 83xx board enabled. I just have MTD_NAND_FSL_ELBC
enabled; it only depends on PPC right now. Attaching the current test
.config, for clarity.

Where did MPC836x_RDK come from above?

I believe that Kconfig warning is misleading. Seems like it should be
saying '||' instead of '&&'. I did not have MPC836x_RDK or
MTD_NAND_FSL_UPM in my .config; only MTD_NAND_FSL_ELBC=y. (Check the
attachment from my previous mail to be sure.)
