# RTEMS BSP Support
#

#
# The RTEMS BSP support requires the host tuple, 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.
#
# Provide the path to the RTEMS tools if not in the prefix with the
# --with-tools option. If --with-tools is not provided use the prefix.
#
# Provide the path to the installed RTEMS kernel if not in the prefix with the
# --with-rtems option. If --with-rtems is not provided use the prefix.
#
# Note, only a single path (--with-rtems) for the RTEMS kernel and any other
# add on or 3rd party libraries is supported.
#

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