Hey,
I have just gone through some of the spec of eMMC, If I have understood properly then eMMC is mean that we can replace our NAND/NOR flash with the device compatible along with eMMC spec (I think OneNand flash by samsung is on the eMMC/eSD spec).
If it's so, then did there is support present on the YAFFS2 file system to support the OneNand flash.
I am asking this query as just on curiosity, sorry if it looks like spam.
