The actual ARM1 processor was built for the "tube" connection on a 6502-based 8-bit BBC Microcomputer in the early 1980s.
These two articles are popular for the details of that history. ARM dominates the second.

I'm pretty sure the grandparent's question was "What IP is on the ARM SOC being fabricated?" and not "Tell me about the history of Acorn RISC Machines".
And the answer isn't clear. The fact that it's been given an Intel code name ("Deer Creek Falls") implies that it's an internal design, so presumably it's an easily-licensed/synthesized core like a Cortex X1 or whatnot. Certainly Intel isn't expected to be designing custom ARM hardware.
