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:
Device: OMAP SD/MMC Manufacturer ID: fe OEM: 14e Name: MMC16 Tran Speed: 52000000 Rd Block Len: 512 MMC version 4.41 High Capacity: Yes Capacity: 13.8 GiB Bus Width: 4-bit User Capacity: 13.8 GiB Boot Capacity: 16 MiB RPMB Capacity: 128 KiB GP1 Capacity: 64 MiB GP2 Capacity: 64 MiB
