36 * Architectures are the sum of the base and extensions. The ARM ARM (rev E)
37 * defines the following: ARMv3, ARMv3M, ARMv4xM, ARMv4, ARMv4TxM, ARMv4T,
38 * ARMv5xM, ARMv5, ARMv5TxM, ARMv5T, ARMv5TExP, ARMv5TE. To these we add
39 * three more to cover cores prior to ARM6. Finally, there are cores which
40 * implement further extensions in the co-processor space.
