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>
