Hello.

The ST-Ericsson Snowball has an eMMC that need a first partition of unknown 
type to make room for some files that the SoC needs in order to boot. We boot 
up to u-boot here, and then proceeds either to the internal eMMC or to the SD 
card, in both cases with the standard boot and root partitions as created by 
Linaro-Media-Create.

When creating images, this first partition is needed for the option 
--image_file, but should not be created for the option --mmc.

We'd like to use the --mmc option to distinguish between these two cases: 3 
partitions vs. 2 partitions.

Some time ago however, I heard a discussion about removing the -mmc option?

Alternatives:

1) The --mmc option stays and keeps it semantics. We depend on it as a 
distinguisher.
2) The --mmc option goes away as we know it, but just drops its parameter and 
is from now on used as a distinguisher for the two cases (I am assuming that 
others can have similar needs)
3) The --mmc option goes away, and --dev <device> gets a second, user-defined 
option --dev <device> <whatever>


BR,
Tony Mansson
