CONFIG_EDAC_MPC85XX is enabled in the that config already. It's just that the mentioned commit broke it because it removed the "select RAS", while EDAC depends on it. So yeah, up to that commit it was always enabled in that particular config. > Oh and we cannot support CONFIG_EDAC_MPC85XX anymore due to lack of hw: > > https://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git/commit/?h=3De= dac-misc&id=3D749c5102487b558cc7d73961a6d0da2fceaa022d Still, it's already enabled in that config and it somewhat recently got IMX9 support, so I guess NXP is interested in keeping it. That being said, I have the hardware, but right now I don't have much time personally. The best I could do is "Odd Fixes". (I also have two pending patches for that edac driver, yet to be posted to the ML). -michael
