target/arm: Implement v8.1M REVIDR register
In v8.1M a REVIDR register is defined, which is at address 0xe00ecfc and is a read-only IMPDEF register providing implementation specific minor revision information, like the v8A REVIDR_EL1. Implement this. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20201119215617.29887-19-peter.maydell@linaro.org
