  right, i can see that and that clarifies things for me. my
*original* question was whether there was a way to set up
/etc/fw_env.config to refer to the eMMC partition /dev/mmcblk1boot1
*directly*, treating it as a regular block partition and bypassing all
the MTD-related processing. (perhaps stefano can weigh in and say
whether that's how he understood what i was asking.)

  if you instead refer to /dev/mmcblk1, as i understand it, you're
just back to the standard MTD-based access, yes?

  anyway, sorry if i didn't explain myself clearly the first time.
