From c5f0d3f1c5078870926ebbc84af92f0f66133cb3 Mon Sep 17 00:00:00 2001 From: Diego Santa Cruz Date: Tue, 23 Dec 2014 10:50:16 +0100 Subject: mmc: show hardware partition sizes in mmcinfo output 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.
