[flashrom] Libflashrom development and integration with fwupd

[artur.raglis at 3mdeb.com]

Hello,

We would like to contribute to the flashrom project by adding missing 
libflashrom
features like queries, proper flashrom_shutdown etc.

Until now, I have implemented and tested missing libflashrom functions 
from
query section [https://www.flashrom.org/Libflashrom] (based on patches 
from
Łukasz Dmitrowski [https://patchwork.coreboot.org/patch/4316/]). There 
are 2
ways to get required information (e.g. supported programmers):

const char **flashrom_supported_programmers(void); //#1
int flashrom_supported_programmers(const char **supported_programmers); 
//#2

I suppose that returning function status (#2) is not necessary with 
query
functions, so I'll stick to the first approach.

What we want to accomplish is remote firmware updates for brand new 
platforms
straight from the factory. To do so, libflashrom will be integrated with 
fwupd
which would control all required lib resources. I have read the 
conversation in
the https://www.mail-archive.com/flashrom@flashrom.org/msg13518.html 
from which
it appears that process callbacks for the progress bar is still high 
priority
task. Are there any new ideas / hints that we need to know for further
development?

Best regards,
Artur Raglis
