Hello,
I tested U-Boot v2017.09 on a Samsung Snow (Chromebook ARM) and while mmc0 (internal eMMC) is working fine, mmc1 (external SD slot) does not work.
I get the following error for 'mmc dev 1' command:
    mmc_init: -110, time 30
Please also note that on boot (or on 1st 'mmc dev 1' cmd if I stop auto-boot), I firstly get:
     mmc_init: -5, time 39
Then, all next attempts retruns:
     mmc_init: -110, time 30

Any idea what could be wrong?
