+; The earliest surviving version of Openmoko fw is moko1, although it is only
+; a binary without symbols.  The present disassembly is a quick look at this
+; binary, dug only far enough to get to the init module.  The objective was to
+; see how the init module of moko1 (presumably coming from TI's 20070419 fw
+; delivery) compares to our familiar 20070608 version, used in moko3 through
+; moko11.  Result: the init module is confirmed to be identical between the two
+; versions, meaning that:
+;
+; 1) Small Samsung flash must have already been adopted by the time of moko1.
+;    If someone were to populate an S71PL129J chip on a GTA01 board and flash
+;    moko1 (or any later version up to moko11) into its first bank, the 2nd
+;    bank on nCS4 won't work because nCS4 is not set up correctly by the MEMIF
+;    setup code in Init_Target().
+;
+; 2) The GPIO bogon functions inserted into the init module were already
+;    present in this 20070419 version.
