Hi Rafael, fixed thanks to the link you gave - needed apatch to a dts
file that limited thge memory available.
So I now have a heavily patched mainline based (gentoo-sources) kernel
with gentoo aarch64/openrc userland running on the n2 as a headless
server for 6 x lxc containers for network infrastructure!
Nice,
BillK

No experience on this, but looks like it can be done with the patched mainline
kernel:

Just for my understanding, gentoo-sources does not contain all the drivers
needed by this board so you are trying to copy those from the 'hardkernel'
sources, correct?

Subject: [gentoo-user] gentoo-sources kernel not seeing 4G ram
Hi, not sure anyone can help with this as its a bit off the reservation :)
I have a Odroid N2 with 4G ram that is only seeing 1G. (even from right at
boot looking at dmesg). Its part of the board so its not a connector issue.
Kernel is gentoo-sources-5.4.8 with the AMLOGIC armv8 relevant bits copied
from the 4.9 series original hardkernel sources. OS is gentoo AARCH64. This
all built and runs quite nicely, but cant see the full 4G ram that should be
there.
Ive attached my latest kernel config in the hope that someone can see
something Ive missed (presuming it isn't an inherent problem in the way I
have gone about this) - looking at the config, diffing it against the hardkernel
source etc. hasn't helped. Below is the start of dmesg up to the memory
statement.
My next move will be to go back to the 4.9 supplied kernel and make sure it
isn't hardware failure (unlikely, but ...)
