Macro to define an Aarch32 (CP15) system register and its fields

Examples

define_aarch32_register!(
    /// This is a aarch32 register
    foo c1, 0, c0, 1 {
        /// This is the field BAR of this register
        BAR OFFSET(0) [
            /// This is a field value of this register field
            VAL1 = 0b1,
            VAL0 = 0b0
        ],
        BAZ OFFSET(1) BITS(2) [
            VAL1 = 0b01,
            VAL2 = 0b10,
            VAL3 = 0b11
        ]
    }
);

    foo::write(
        foo::BAR::VAL1 | foo::BAZ::VAL2
    );
