+TODO
+====
+
+The OpenRISC Linux port is fully functional and has been tracking upstream
+since 2.6.35.  There are, however, remaining items to be completed within
+the coming months.  Here's a list of known-to-be-less-than-stellar items
+that are due for investigation shortly, i.e. our TODO list:
+
+-  Implement the rest of the DMA API... dma_map_sg, etc.
+
+-  Finish the renaming cleanup... there are references to or32 in the code
+   which was an older name for the architecture.  The name we've settled on is
+   or1k and this change is slowly trickling through the stack.  For the time
+   being, or32 is equivalent to or1k.
