My thinking could be missing something or wrong, but I think other arm folks could also comment on that. thanks, Ganbold > >> >> Ganbold >> >> >> >>> >>> Alexander Fedorov >>> _______________________________________________ >>> freebsd-arm@freebsd.org mailing list >>> http://lists.freebsd.org/mailman/listinfo/freebsd-arm >>> To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org" > _______________________________________________ > freebsd-arm@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-arm > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org"
