Does this mean it may be possible to run basic version of C5, C6 and C7 on Arm64* CPU systems ? Presumably this will include the Raspberry Pi ?
* Acorn Research machines; manufacturers of the BBC Models A, B, B+, Master 128 etc - those were the days.

is the rasberry pi ARMv8 (arm64) ? I thought it was v7 (32bit only)

You are correct, the Pi is not armv8.
This is for larger devices ... although, there are now a some armv8 embedded devices too.
We SHOULD also have an armv7hl branch at some point too (we have just really started working on that) ... and I think that will run on the raspberry pi2 when done (though not the original).
We are trying for large data center devices not cell phones :)

I would assume there's more than JUST the CPU instruction set architecture at play here... system boot firmware, and IO device controller support must play a part in this?

Raspberry Pi 2 Model B is the second generation Raspberry Pi. A 900MHz quad-core ARM Cortex-A7 CPU 128-bit AMBA® 4 AXI bus interface.
The Cortex-A7 processor builds on the energy-efficient 8-stage pipeline of the Cortex-A5 processor. .... with 64-bit load-store path, 128-bit AMBA 4 AXI buses and increased TLB size (256 entry, up from 128 entry ....
ARMv7-A
The MPE extends the Cortex-A7 processor's FPU to provide a quad-MAC and additional 64-bit and 128-bit register set supporting a rich set of SIMD operations over 8, 16 and 32-bit integer and 32-bit Floating-Point data quantities.

Except for the above, can't find any specific mentioned of 32 or 64 bit CPU.

ARMv7-A is 32 bit .. We are currently building for some of the listed ARMv8-A systems with our AArch64 architecture.
The RSEL Project has working builds of EL6 and 7 out for embedded ARM devices like the raspberry pi. http://www.redsleeve.org
You need to dig through their wiki four instructions your several devices. Am 14.05.2015 23:46 schrieb "Johnny Hughes" johnny@centos.org:

Vielen dank. The site is currently unreachable. The owner says it will be working this evening. He told me it runs on an ARM.

No. What I'm working on is 64bit/ARMv8 only. If you want something that's similar form factor to the rpi, you might check out
https://www.96boards.org/products/hikey/
It *should* run on that. I haven't tested this yet, so I can't say for certain. I should have one of these fairly soon though, and will then be able to give a definite answer.
Fabian is working on an ARMv7(32bit) build that will support things like the odroid, and rpi2.
