hm...
It seems that the changes never reached upstream:
git://github.com/01org/edison-u-boot.git branch edison-v2014.04
this branch was implementing 'part info' sub-command which was useful to
retrieve partition info.
the new repo:
git://github.com/edison-fw/u-boot.git branch acpi-v2020.04 does implement
'part number' but does not implement neither 'info' or 'block'.
I do not insist for you to take this patch, but I think it is useful (it is
the simplest version which supports all needed functionality).
If you think the same, let me know. I can change name of the sub-command or
implement this in a different way, if needed.
Thank you,
Razvan
