-When adding a BSP to the RTEMS tree, there is usually some cleanup
-to be done. 
-
-=========================================================================
-
-Add an entry to ACKNOWLEDGEMENTS.
-
-Send letter with permission to distribute the BSP with RTEMS.
-
-Verify all test link.
-
-Remove compilation warnings.
-
-Make sure that all files submitted are really intended to do into
-the distribution. For example, you may have a myfile.S produced by
-gcc -S myfile.c.
-
-=========================================================================
-This section of the file describes how to run the acpolish script to
-check Makefile style and construction compliance.
-
-The BSP's still apply RTEMS's old autoconf configuration. The only thing
-that have changed are some details inside the Makefile.ins and some details
-in make/custom/<bsp>.cfg. Acpolish should be able to convert 4.0.0
-Makefile.in into new style Makefile.ins. However, sometimes acpolish has
-problems/contains bugs, which require manual intervention. There is no tool
-to adapt a BSP's <bsp>.cfg, but this shouldn't be a problem for you.
-
-Therefore, this is my coarse recipe to merge BSPs is:
-
-1. Copy a BSP's files and directories to appropriate directories.
-
-2. Manually run acpolish on each Makefile.in and check the output, eg:
-cd some_subdir
- /path_to_RTEMS/tools/update/acpolish < Makefile.old > Makefile.new
-
-Check Makefile.new for correctness, evtl. edit it, then re-run acpolish
-again:
-/path_to_RTEMS/tools/update/acpolish < Makefile.new > Makefile.in
-
-Compare Makefile.new against Makefile.in. These must not differ, if they
-do, edit Makefile.new until the Makefile.in generated by re-running
-acpolish on Makefile.new does not differ from the freshly generated
-Makefile.in. If they differ permanently, then you probably are affected
-bugs in acpolish (This happens for some styles of conditionals).
-
-This sounds much worser than it actually is, because the bugs in acpolish
-only hit very seldom. Furthermore, BSPs normally only contain a few
-Makefile.ins, therefore individually running acpolish should be tolerable.
-
-3. If a BSP contains tools, you have to convert its configuration to
-automake manually. Typically these tools are rather simple, therefore a
-tool's configuration applies standard automake Makefile.ams and
-configure.ins. RTEMS should contain enough examples which could serve as
-templates for this (My advice: Try to avoid preinstallation and
-installation to the temporary installation tree whenever possible; Don't
-forget to add all sources which do not get installed by automake
-to automake's EXTRA_DIST, e.g. noinst_SCRIPTS, noinst_DATA have to be added
-to EXTRA_DIST.
-
-Please let me know if you meet problems and if we/I can fix them. I
-consider acpolish to be an internal developer's and maintainer's helper
-script, which was never intended to be of general use, which is why I am
-not much concerned about bugs in it.
-
-Ralf.

-Board Support Package library
-
-This directory contains the source for the libbsp.a library.
-For each supported board $(RTEMS_BSP) there is a standard
-set of functions which must be provided in the BSP:
-
-   + start up initialization
-   + exit support
-   + set vector
-   + console IO support
-   + drivers
-
-In addition, the BSP also determines the memory usage by providing
-any necessary linker scripts.
-
-There are also "generic" drivers in this directory.  Currently
-they are shmdr and stubdr.
-
-Some of the supplied generic drivers (for example, shared memory) require
-target board specific support routines.
-
-NOTE: The library libbsp.a is actually built by $(RTEMS_BSP)/wrapup/Makefile.
-
-To execute all of the test in the RTEMS Tests Suites the following
-device drivers must be supplied:
-
-   + Clock Tick
-   + IO Driver Support
-   + Timer
-   + Shared Memory Driver Support
-
-The Timer Driver is used only by the Timing Test Suite (c/src/tests/tmtests/*).
-These tests are used to generate the execution times for RTEMS found in the
-flyers.  It is recommended that these tests be run to verify a port to a new
-CPU or with a newly developed BSP.  Looking at the times as compared to a
-known CPU and target can yield insights into potential performance problems
-in either the port, the BSP, or the target hardware.
-
-The Shared Memory Support is only required to execute the Multiprocessor
-Test Suite (c/src/tests/mptests/*).  Multiprocessing is not a required part
-of a BSP.
