Yes please go ahead, no objection from me. Also related, the 2430 support could be dropped as AFAIK there are no active users for it. It's similar to the 2420 support that n8x0 use, and only 2420 support should be kept. > The effect here would be that imx_v6_v7_defconfig would > only inlucde imx35 but not imx31, and that omap2plus_defconfig > would turn into effectively omap3plus. Yes that makes sense for the active devices. Note that multi_v7_defconfig is too bloated to boot many of these devices.. > I would still tentatively schedule both for removal in early > 2026, but if we add the !SMP dependency it's not a big deal to > keep them around after that either.
