[PATCH v1 0/4] aarch64: add new Armv9.5-A features and their associated registers (RAS, Debug, Performance Monitor)

[Matthieu Longo]

Hi,

[patch 0/4] aarch64: aarch64: add new Armv9.5-A features and their associated registers (RAS, Debug, Performance Monitor)
    [patch v1 1/4] aarch64: add E3DSE feature and its associated registers
    [patch v1 2/4] aarch64: add SPMU2 feature and its associated registers
    [patch v1 3/4] aarch64: add STEP2 feature and its associated registers
    [patch v1 4/4] aarch64: add Debug Feature Register 2 (ID_AA64DFR2_EL1)

AArch64 defines new registers for Armv9.5-A architecture.
This patch series adds the following features and their associated system registers:
- e3dse (Delegated SError exceptions for EL3)
- fpmu2 (System Performance Monitors Extension version 2)
- step2 (Enhanced Software Step Extension)
- ID_AA64DFR2_EL1 (Debug Feature Register 2)

Each patch also adds relevant tests.
Regression tested on aarch64-none-elf, and no regression found.

Ok for binutils-master?

Regards,
Matthieu.
