Dell DW5570 firmware upgrade with qmi-firmware-update

[Aleksander Morgado]

Hey,

Ok, not really something much new because the Dell DW5570 is a
rebranded Sierra MC8805 module, but anyway.

======================

Getting the firmware:
 * I went to the Dell website and found a page providing "Dell Update
Package for driver installer supporting DW5570 Mobile Broadband
module".
 * In this page I got a "556WW_A00_build3843_Setup_ZPE.exe" file,
which I extracted with "7z x ...".
 * Then I got a Setup.exe, which I also extracted with "7z x..."
 * I got quite more things but among them, a directory named "Images":
$ find Images/8805/
Images/8805/
Images/8805/Generic
Images/8805/Generic/6
Images/8805/Generic/6/ImageInfo.xml
Images/8805/Generic/6/spkgz.cwe
Images/8805/Generic/6/carrier_pri.nvu
Images/8805/Generic/7
Images/8805/Generic/7/ImageInfo.xml
Images/8805/Generic/7/spkgz.cwe
Images/8805/Generic/7/carrier_pri.nvu

======================

The Generic/6 images (cwe and nvu) provide the default firmware that
my device already had: modem image SWI9X15C_01.08.16.03, pri image
01.08.16.02 001.009_000 GENEU (note the firmware version mismatch!
first time I really needed --ignore-version-errors).

The Generic/7 images (cwe and nvu) provide modem image
SWI9X15C_01.08.16.02, pri image 01.08.16.02 001.005_000 TELEFONICA.

======================

NOTE: had to patch qcserial driver to support 413c:81a6, the vid:pid
of the modem when in QDL download mode; already submitted to linux-usb
mailing list.

    NOTE: in order to validate which is the firmware running in the
    module, the program will wait for a complete boot; this process
    may take some time and several retries.
