The Ampere1B is Ampere's third-generation core implementing a superscalar, out-of-order microarchitecture with nested virtualization, speculative side-channel mitigation and architectural support for defense against ROP/JOP style software attacks.

Ampere1B is an ARMv8.7+ implementation, adding support for the FEAT WFxT, FEAT CSSC, FEAT PAN3 and FEAT AFP extensions. It also includes all features of the second-generation Ampere1A, such as the Memory Tagging Extension and SM3/SM4 cryptography instructions.

This provides basic enablement (reusing the scheduling model from Ampere1).
An updated scheduling model will be added as a separate commit.

The clang-format failures are caused by preexisting/unchanged code.
All newly added code passes clang-format.

Yes, I had this issue when I landed new cores previously. This whole file needs an NFC clang-format cleanup, IMHO.

[AArch64] Add the Ampere1B core
257576a 
The Ampere1B is Ampere's third-generation core implementing a
superscalar, out-of-order microarchitecture with nested
virtualization, speculative side-channel mitigation and architectural
support for defense against ROP/JOP style software attacks.

Ampere1B is an ARMv8.7+ implementation, adding support for the FEAT
WFxT, FEAT CSSC, FEAT PAN3 and FEAT AFP extensions.  It also includes
all features of the second-generation Ampere1A, such as the Memory
Tagging Extension and SM3/SM4 cryptography instructions.
