deci IS an SI prefix, as well as centi, deca and hecto (i.e. 10^+/-1,
10^+/-2), but i have to agree with peter: it does not make a lot of
sense to be that petty on (constant/text segment) space usage imho.
if that information is deemed too big, then it should not be in there at
all.
where/when do you think it gets in the way of using flashrom? we could
use a macro similar to the ones used for hiding certain board
information triggered by CONFIG_PRINT_WIKI in print.c for flashchips.c
this could actually be a good idea, because we could then create
different macros for different bus types and ensure that all important
fields for that bustype are initialised.
