SubjectRe: [PATCH v4 1/2] ARM: socfpga: support suspend to ram

Do we went to have the dependency at the .config time? We would like
to do generic kernels booting on many machines, this kind of breaks
that...

Which bootloaders can do that?

Would it make sense to configure it in Linux?

Thanks,
Pavel
