+This dir contains useful patches for things that are not part of the
+normal base release.
+
+Currently we have:
+
+1) the VLIO patches for bootldr and vhdl. You need both
+of these or it won't work at all! Change the VHDL first, not the
+bootloader when uploading binaries, otherwise you can brick your
+balloonboard to a 'needs JTAG' state.
+
+2) The TCL serial logic patch which patches Com1 serial through to the
+pinko connector instead of the normal one. This logic is incompatible
+with other hardware so can not be in by default.
