Ping?
The very old age of the firmware files in linux-firmware is really
UNACCEPTABLE and very irresponsible from a security POV. Please
fix this very soon.
If you do not reply to this email I see no choice but to switch
the firmwares in linux-firmware over to the ones from the SDK which
you do regularly update, e.g. those from:
https://community.cypress.com/docs/DOC-19000
Yes those are under an older, slightly different version of the Cypress
license, which is less then ideal, but that license is still acceptable
for linux-firmware (*) and since you are not providing any updates to
the special builds you have been doing for linux-firmware you are
really leaving us no option other then switching to the SDK version
of the firmwares.
Regards,
Hans
*) We have distributed files under the old version of the license before
