Not in any mainline code, it seems.
i didn't think so, just wanted to make sure.
i can see the commit that did a rename:
commit 90a92a708d5180a20d600ba0fc2352ec76dc3829 Author: Jean-Christophe PLAGNIOL-VILLARD plagnioj@jcrosoft.com Date: Fri Mar 27 23:26:42 2009 +0100
at91: rename DATAFLASH_MMC_SELECT to CONFIG_DATAFLASH_MMC_SELECT Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>but unless *someone* defines that macro, is it doing anything useful? or am i just confused?
Eventually JC had some patches on his famous stack before he threw in the towel.
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?
