Like I said, it's shoddily written.

If the author wanted to convey "ARM v7 processors" as including Snapdragon/A4/OMAP, he should have written it that way, not in one that is indicative of a category, being x86, and the objects within it, being Snapdragon/A4/OMAP.

"600MHz+ x86-based or ARM-based processors (including Snapdragon, A4, OMAP and ST U8500)".
