  i didn't think so, just wanted to make sure.

  so does that mean that DATAFLASH_MMC_SELECT-related content can be
removed -- at least for now until someone else comes along and tries
to put it back and make it useful?   obviously, it's not doing any
actual harm being there, it just has no value.  at the moment:

$ grep -r DATAFLASH_MMC_SELECT *
board/atmel/at91rm9200dk/Makefile:COBJS-$(CONFIG_DATAFLASH_MMC_SELECT) += mux.o
board/atmel/at91rm9200ek/Makefile:COBJS-$(CONFIG_DATAFLASH_MMC_SELECT) += mux.o
CHANGELOG:    at91: rename DATAFLASH_MMC_SELECT to CONFIG_DATAFLASH_MMC_SELECT
common/Makefile:COBJS-$(CONFIG_DATAFLASH_MMC_SELECT) += cmd_dataflash_mmc_mux.o
include/at45.h:#ifdef	CONFIG_DATAFLASH_MMC_SELECT
$

which suggests that, if one removes that CONFIG variable, there are a
couple source files that can go with it.

  i can trivially whip up a patch that takes all that out, unless
someone wants to argue to hang onto it for, say, future
consideration or something.  thoughts?  does someone from atmel have
an opinion on this?
