fxload to restictive with address range

[Kay Sievers <lkml001@vrfy.org>]

Hello,
i have a DSL-USB-Modem:
http://www.devolo.de/produkte/adsl/mladslfunusb/index.php

inside is the 6485 Chip from Aanalog Devices:
http://www.analog.com/Analog_Root/productPage/productHome/0%2C2121%2CAD6485%2C00.html

A part of the chip is some kind of ezusb 8051.
(in the same chip is Ethernet and DSL-Pump)

I have extracted the firmware by sniffing Windows USB,
then converted to Intel-Hex-File.

I've successfull loaded the firmware into the device with a modified fxload.
Unfortunately fxload does not support the address range of this chip.
I changed the following lines and everything is working well.

                return -5;
            } /* else OK */


I expect more devices of this kind to appear in the future.
Maybe somebody can check, how to be prepared for larger RAM sizes.


Have a good day
