https://www.solid-run.com/introducing-helios4-personal-cloud/ is
announcing it from SolidRun it is based on https://www.solid-run.com/ma
rvell-armada-family/armada-som-system-on-module/ the one used in the
helios4 has 2GiB of ECC ram. The microsom is split out in the kernel
dts files https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linu
x.git/tree/arch/arm/boot/dts/armada-38x-solidrun-microsom.dtsi

ECC is enabled and working, it had not been earlier.
