should all SD-bootable boards have CONFIG_MCI_WRITE enabled?

[Robert P. J. Day]

  with boards like the beagle and panda that can boot off of SD cards,
shouldn't all boards like that have CONFIG_MCI_WRITE enabled so that
one could write the environment back with "saveenv"?

  currently, omap3530_beagle_defconfig *doesn't* have that set, which
produces (on my xM):

barebox@Texas Instrument's Beagle:/ saveenv
saving environment
could not open /dev/env0: Read-only file system

  now, that *could* be because i have no /dev/env0 file given how my
environment was configured (i have only /dev/defaultenv), but even if
i did have a /dev/env0, wouldn't i still need MCI_WRITE to save my
environment?

  the obvious proposed patch is to add CONFIG_MCI_WRITE=y to both the
beagle and panda defconfig files.  does that sound right?  any other
boards for which that would be appropriate?
