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?
I think that this is what you mean: https://bugs.launchpad.net/linaro-image-tools/+bug/744449 and would let l-m-c only create images with the option of writing it to mmc.
The support for different SD layouts in hwpacks in in this spec which I'll be working on now: https://wiki.linaro.org/Platform/Specs/11.05/HardwarePacksV2. At least I guess the proposed field partition_layout would support what you want to do.
Thanks,
