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.
