There is currently no command that will provide an overview of the hardware partitions present on an eMMC device, one has to switch to every partition via "mmc dev" and run mmcinfo for each to get the partition's capacity. This commit adds a few lines of output to mmcinfo with the sizes of the present partitions, like this:
