# RTEMS BSP Support
#

#
# The RTEMS BSP support requires the host turple, the RTEMS BSP and the path to
# the tools. The prefix is set to an installed RTEMS. The built package is
# installed into the prefix.
#
# Keeping the package's installed path in the RTEMS install path and separate
# to the tools lets the tools version vary independently. If --rtems-tools
# (--with-tools) is not provided use the prefix.
#

#
# If a dry-run and with download ignore errors and correct setting for tools
# and BSPs. Only after the source to download.
