From: Ciprian Marian Costea <ciprianmarian.costea@xxxxxxxxxxx>
With respect to S32G2/S32G3 SoC based boards, there are multiple RDB
(rdb2 vs rdb3) and EVB (for G2 vs for G3) board revisions. These versions
are quite similar. The common part for the EVB revisions will be
centralized in 's32gxxa-evb.dtsi' file, while the RDB commonalities will
be placed in 's32gxxa-rdb.dtsi' file.
This refactor will also serve for other modules in the future, such as
FlexCAN, DSPI.
