Why not return SYSINFO_ID_BOARD_REVISION as integer here ?


Because the revision (on r-car3 boards at least) is in the format X.Y.
It
could be returned as "(X << 8) | Y" or split in major/minor. But
different
boards will use different revisions and I think that having a str is
easier to deal with in a shell script.


With rcar they are numbers, so lets go with major/minor integers
please.


Ok for this part, but shouldn't the sysinfo command use a common
interface
for all boards ? Or should it also have rev_major/rev_minor arguments ?


I would expect other boards to either report rev_major/rev_minor if
implemented, or errno if those boards don't implement this property.


Another thing on rcar is that the revision is stored as 2 char values.
Would you oppose a change form using a char (e.g. rev_major = '1') to
using u8 values (e.g. rev_major = 1) instead ?


Shouldn't those rev fields just be integer(s) to cover the generic case?


On rcar, they are chars. I don't really see a reason for this except to show
the '?.?' on unknown board ids. But that can be managed in other ways.


Yes I know, I am more concerned about other boards which might not have 
such short revision number, so why not just make the revision fields 
integer which covers very much anything ? Also, if you have those fields 
set to integer, then -EINVAL could be printed as '?' .

Because the revision (on r-car3 boards at least) is in the format X.Y. It 
could be returned as "(X << 8) | Y" or split in major/minor. But different 
boards will use different revisions and I think that having a str is easier to 
deal with in a shell script.

Why not return SYSINFO_ID_BOARD_REVISION as integer here ?
