# TODO: currently we cannot support parallel builds since some fusesoc cores
# define filesets with files outside the current folder (e.g. using relative
# path prefixes such as "../../"). this can cause collisions between parallel
# builds since they are not nicely contained within the same folder. This should
# be solved by reworking the fusesoc core files (especially the top-level one).
