[Qemu-devel] [PULL 42/49] target/arm: Define FIELDs for ID_DFR0

[Peter Maydell]

From: Aaron Lindsay <address@hidden>

This is immediately necessary for the PMUv3 implementation to check
ID_DFR0.PerfMon to enable/disable specific features, but defines the
full complement of fields for possible future use elsewhere.
