I should probably fix that. Sadly, I don't have this old hardware anymore. I have lent my first generation beagleboard to another person several years ago and have no idea where it is now. Maybe I should try to get it back one day :) But taking the "formal" route, I checked who is the current beagleboard maintainer and looks like that's Tom Rini, who is already quite conveniently in the CC ;-) Basically, this old hardware is either maintained or not. If it is maintained, then probably the board maintainer is the best person to review and test the errata patches. > I will hold off adding more erratas or changes for now and look for > the current series getting in.. in fact, I am tempted to remove omap3 > entirely from this list for now, given the multiple platforms impacted > and unless folks are willing to help test those, I am more than happy > to just focus on a15 erratum in the first series which benefits my > immediate needs and potentially helping exynos as well. -- Best regards, Siarhei Siamashka
