Dear all,
this is a release to the community of the source code of the utility
lsmmc, created by Sebastian Rasmussen formerly at ST-Ericsson.
lsmmc contains an extensive parser of the CID, CSD, SCR and EXT_CSD
registers, as well as an archive of these registers for over 120
eMMC and SD-cards.

Hello Ludovic,
I have tried it with atmel-mci driver. It took me little time to change setting
of my board.
It seems to try clock down to 200kHz:

[5.92] mmc0: mmc_rescan_try_freq: trying to init card at 30 Hz

According to eMMC spec, the command's completion time is
not dependent on OUT_OF_INTERRUPT_TIME. Only the transition
out of PRG STATE is guarded by OUT_OF_INTERRUPT_TIME - which is
