[mc1322x] Access to LQI

[Clive Stubbings]

Hi Mar,

That didn't work. I'm guessing that the rom call isn't compatible with your 
wireless code - or the address is wrong, or the call in the s/w build I have 
is different from the one into ROm... or whatever..

Not done any RE for a long time... Is there a dis listing that people are 
working on somewhere? I'm presuming the ws-dis and mc..img are ram only.

Cheers
Clive
