The BeagleBone Black (aka "BBB") is recommended by the Libreboot developers for use with Flashrom: "We recommend this product because we know that it works well for our purposes and doesn't require any non-free software." https://libreboot.org/docs/install/bbb_setup.html
However, it is missing from the "Supported programmers" page of the Flashrom wiki: https://www.flashrom.org/Supported_programmers
This is quite a surprising omission, given the fact that it is recommended by Libreboot.
It does seem to have been given some cursory attention on the Flashrom wiki here: https://www.flashrom.org/BBB .
If anyone who has a BBB and has write access to the Flashrom wiki feels like fleshing out the latter page and linking it from the "Supported programmers" page, this would probably be very helpful for (potential) BBB owners who might not otherwise realise that Flashrom supports the BBB.
