+# All text after a double hash (##) is considered a comment and is placed in
+# front of the TAG it is preceding.
+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:

+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text

Modification to include/public/grant_table.h:
1) Add doxygen tags to:
- Create Grant tables section
- include variables in the generated documentation
- Used @keepindent/@endkeepindent to enclose comment
section that are indented using spaces, to keep
the indentation.
2) Add .rst file for grant table
Signed-off-by: Luca Fancellu <luca.fancellu@arm.com>
