This patch adds time measurement and throughput calculation for the ext2load and ext4load commands.
The output of ext2load changes from
---8<--- Loading file "/boot/uImage" from mmc device 0:1 1830666 bytes read --->8---
to
---8<--- Loading file "/boot/uImage" from mmc device 0:1 1830666 bytes read in 237 ms (7.4 MiB/s) --->8---
Signed-off-by: Andreas Bießmann andreas.devel@googlemail.com --- since v1: * use 'time' instead of 'time_start' as suggested by Wolfgang
