I am open to add this, but I really don't want to see tons of different "drivers" to read this data added to systemd. Hence the way I think this should work, is adding a generic interface to the kernel to /sys/firmware/timing or so, where this information can be read from. We'd then make systemd read that. And wherever the information comes from would be a kernel internal decision, and could be implemented in a myriad of different ways for different architectures. Also note that ACPI 5.0 exports this timing information in a generic way anyway. Given that ACPI is fairly standard and apparently is even what embedded is standardizing on I'd be open to adding native support for parsing this info from ACPI to systemd, if it's easy enough. However, beyond that: please abstract this in the kernel, I don#t want to see tons of drivers for this in systemd.
