It is not responsible... it IS the flash chip ;)
But according to this change notification it might not be true:

No idea which SST chip they used... but i guess both should be
supported by flashrom. No idea why it is not detected.

Someone with more knowledge about FWH than me has to look at it. It
would certainly help if we would know which flash chip is really inside
it...
