Move TCL script files -- Step 2 of 2:

- Move src/tcl to tcl/.
- Update top Makefile.am to use new path name.

+# MEMORY 
+#
+# All Memory regions have two components.
+#    (1) A count of regions, in the form N_NAME
+#    (2) An array within info about each region.

+# The ARRAY
+#
+#       <NAME>(  RegionNumber ,  ATTRIBUTE )
+#
+# Where <NAME> is one of:
+#
+#     N_FLASH  & FLASH   (internal memory)
+#     N_RAM    & RAM     (internal memory)
+#     N_MMREGS & MMREGS  (for memory mapped registers)
+#     N_XMEM   & XMEM    (off chip memory, ie: flash on cs0, sdram on cs2)
+# or  N_UNKNOWN & UNKNOWN for things that do not exist.
+#
+# We have 1 unknown region.
