If the firmware upgrade code are same for 9117-570 and 9110-510?

When I try to download firmware for pseries (power5 cpu), I found it seems the firmware upgrade code are same for 9117-570 and 9110-510. If they are the same current firmware level and want to upgrade to same firmware.

Am I right?

Because it descript:
This package provides new firmware for OpenPower, i5 and p5 Servers, System i, System p and IntelliStation 285.

If that means all of above model use same firmware?

Yes the SF240_358 is the recommended level by IBM for both systems and the SF240_382 is the latest level available.

Thank you!

If that means I only need download one SF240-358 source code and then can upgrade 9117-570 and 9110-510 both?

Yes that's correct. I've upgraded our P5 570's, 520's, and 52A's using the same firmware code.
