Ok. That's quite simple :)
I found somewhere, that CPLD is located at physical address 0x10000000.
So I started haret and dumped that region. (pd 0x10000000 1024).
It's easy to notice, that pattern is repeating every 32 bytes, so we can
focus on address space 0x10000000-0x1000001F.
First attempt was to set all this to 0x00 (pfw 0x10000000 8 0x00000000),
then to 0xFFFFFFFF...
You have to be patient and ready to reboot loox if something bad happens
(it does! ;))
By changing address and length of region being set you can observe many
different behaviours... and that's it.
Finally you can tell: this bit, at this location disables WiFi (i use
haret via wifi so it's easy to notice ;)), this enables backlight etc...
Same with USB - normally when you connect/disconnect PDA to linux box
you get messages (dmesg). After disabling one of bits @0x10......
desktop can't see PDA.
