1 ; The earliest surviving version of Openmoko fw is moko1, although it is only
2 ; a binary without symbols. The present disassembly is a quick look at this
3 ; binary, dug only far enough to get to the init module. The objective was to
4 ; see how the init module of moko1 (presumably coming from TI's 20070419 fw
5 ; delivery) compares to our familiar 20070608 version, used in moko3 through
6 ; moko11. Result: the init module is confirmed to be identical between the two
7 ; versions, meaning that:
8 ;
9 ; 1) Small Samsung flash must have already been adopted by the time of moko1.
10 ; If someone were to populate an S71PL129J chip on a GTA01 board and flash
11 ; moko1 (or any later version up to moko11) into its first bank, the 2nd
12 ; bank on nCS4 won't work because nCS4 is not set up correctly by the MEMIF
13 ; setup code in Init_Target().
14 ;
15 ; 2) The GPIO bogon functions inserted into the init module were already
16 ; present in this 20070419 version.
