[PATCH 1/2] arm: mvebu: clearfog: add SCSI to distro bootcmd

[Joel Johnson <mrjoel@lixil.net>]

As with other related ClearFog patches, I haven't received any review 
responses on this series 
(http://patchwork.ozlabs.org/project/uboot/list/?series=155760) and 
would like to ping out for additional review. I'd especially like 
feedback on the approach for support of multiple SCSI devices, if there 
a preferred or standardized mechanism I'd be happy to adjust, but I 
couldn't find any other examples of including multiple SCSI devices in 
distro_boot. In reviewing again myself there was an initial mental 
mismatch between CON2/CON3 usage as connection ports and the naming of 
SCSI_CLEARFOG2/SCSI_CLEARFOG3 as index counters, but otherwise still 
seems good.

If it's in an acceptable state for inclusion in the next merge window, 
that's certainly fine too, I'm just looking for a crosscheck.

Thanks!
Joel
