I think so. It looks like the other lines were meant to be byte
selects for NOR/UPM, not anything to do with the chip select.

I guess not, especially if that's the only way the FCM works.

But to be sure, maybe ask official Freescale support channels, and/or
someone who's more familiar with the hardware side of this stuff.
