Note on ARM documents:

Both infocenter.arm.com and developer.arm.com are outright nightmares to navigate, and search engines don't help either. But if you have any ARM document as a PDF and want to check for a newer version, there is a neat trick. At the bottom of any page of the PDF, you should have a document identifier like so:

That should have the form ARM XXX ddddX.x. Take the three letters and following four digits (in this case, DDI0406) and construct an URL like so:
https://developer.arm.com/docs/XXXdddd/latest
(In this case, https://developer.arm.com/docs/DDI0406/latest.)
