Commit Message

Marek Vasut Oct. 25, 2024, 10:55 p.m. UTC 
Deduplicate defconfigs for all DH i.MX8MP DHSOM by factoring out the
common parts into generic _dhsom_defconfig and including those using
the #include <configs/...> preprocessor macro, which is applicable to
defconfigs as well. This enables CMD_EXPORTENV on all iMX8MP DHSOM
systems to be consistent with other DHSOM systems.
