# a list of MX drivers that only includes the actual drivers we need.
# You must also edit libMx/mx_driver_rtems.c to match.
#
# The following is just an example.  You should customize it to match
# the configuration you actually need.

# WARNING: I am not currently sure if the following information is correct,
#          since my MVME162 is currently not booting with RTEMS.
#
# MVME162 Note:
#   The linker command file /opt/rtems-4.6/m68k-rtems/mvme162/lib/linkcmds,
#   as distributed, comes configured for 1 megabyte of RAM.  This is not
#   enough to run MX, so you must change the specified amount of RAM to
#   match the actual board you have.  MX has only been tested with RTEMS
#   on the 16 megabyte MVME162-532A, which has more than enough memory.
#
#   The lines that need to be changed are:
#
#       _RamSize = DEFINED(_RamSize) ? _RamSize : 1M;
#
#   and
#
#       ram : org = 0x000000, l = 1M
#
#   where you must replace the 1M with the actual amount of memory you have.
#   For example, 16M for the MVME162-532A mentioned above.
#
#   If you really only have 1 megabyte of RAM in your MVME162, then you
#   are out of luck and cannot run MX on it.

# Most BSPs actually provide even more definitions.  Look in the
