I thought the 64bit ARMs were usually "ARMv8", not "ARM 7"? In fact, doesn't "ARM 7" mean a series of ARMv3 and ARMv4 CPUs? (The pi1 and pi2 had ARMv6 and ARMv7 cores I believe)

There's a huge difference between "ARM 7" and "ARMv7". Even if it's a typo (missing "v"), it's odd it's not v8?

You are correct. The naming scheme is confusing as heck. When Android device manufactures transitioned to armv7, a dev tools company I worked with at the time made the decision to drop armv5/armv6 support. But users were absolutely confused by this, because device manufacturers continued pushing the marketing names. The worst for us was ARM11, which was like a dual armv6, because cheap device manufactures continued pushing new devices based on this instead of moving to armv7.

Indeed a typo, it's ARMv7 and it's indeed 64 bits according to Farnell: http://www.farnell.com/datasheets/2020826.pdf

Strangely enough, this PDF appears to be a completely empty document. All I get is a blank, 1/1 page. Have to regard it as, well, not informative...

(Let's hope whatever the error, it gets fixed.)

I've never heard of a 64-bit armv7. So I decided to look it up. Looks like this Reddit thread already said a lot of these things, i.e. armv7 is 32-bit, the document is blank, one of these things (armv7 or 64-bit) is an error:

Arm7 is a 32-bit architecture: https://en.wikipedia.org/wiki/ARM7
