[PATCH v1] Add steps to test Newlib patch.

[Vaibhav Gupta]

Update the checksum to be used for the Newlib patches.
Earlier it was msd5, but it is depreciated for security
reasons. Now RSB accepts sha512.

 To test a patch simply copy it to your local ``patches`` directory. The RSB
 will see the patch is present and will not attempt to download it. Once you are
 happy with the patch submit it to the project and a core developer will review
-it and add it to the RTEMS Tools git repository.  For example, to test a local

+Testing a Newlib Patch
+~~~~~~~~~~~~~~~~~~~~~~
+
+To test a local patch for newlib, you need to add the following
+two lines to the ``.cfg`` file in ``rsb/rtems/config/tools/`` that is included
+by the bset you use:
+
+.. topic:: Steps:
+
+  1. Create patches for the changes you want to test. (Note: For RSB, before
+     creating Newlib patch, you must run ``autoreconf -fvi`` in the required
+     directory after you make changes to the code. This is not required when
+     you create patch to send to ``newlib-devel``. But if you want RSB to 
+     address your changes, your patch should also include regenerated files.)
+
+  2. Calculate ``sha512`` of your patch.
+
+  3. Place the patches in ``rsb/rtems/patches`` directory.
+
+  4. Open the ``.bset`` file used by your BSP in ``rsb/rtems/config``.
+     For example, for ``rtems5``, ``SPARC``, the file will be
+     ``rsb/rtems/config/5/rtems-sparc.bset``.
+     
+  5. Inside it you will find the name of ``.cfg`` file for Newlib, used by
+     your BSP.
+     For example, I found ``tools/rtems-gcc-7.4.0-newlib-1d35a003f``.
+     
+  6. Edit your ``.cfg`` file. In my case it will be,
+     ``rsb/rtems/config/tools/rtems-gcc-7.4.0-newlib-1d35a003f.cfg``. And
+     add the information about your patch as mentioned below.
