@ThinkOpenly Thanks for the feedback! I’ve made the following updates:

• Updated descriptions to match the ratified spec for mcyclecfg and minstretcfg.
• Combined location_rv32 and location_rv64 into a single line.
• Adjusted the inhibit bit descriptions to align with the spec wording.
• Added base: 64 to both YAML files.
• Ensured bit 63 is read-only zero
  Let me know if anything else needs attention!

@ThinkOpenly I'll update the PR by adding mcyclecfgh and minstretcfgh, using a table format for privilege modes, and ensuring consistency in the comments and formatting across the YAML files.Thanks for the suggestion, and sorry for the oversight!

Will you be adding mcyclecfgh and minstretcfgh? These are the 32-bit (high) versions of these registers, so very similar definitions.

Thank you for the detailed feedback, and apologies for the earlier confusion. I've now made the following updates:

• Added mcyclecfgh and minstretcfgh CSR YAML files as the 32-bit high halves for RV32.
• Corrected mcyclecfg and minstretcfg:
  • Removed base: 64 at the register level.
  • Added base: 64 to individual fields at locations ≥ 32.
  • Converted field type attributes to type() functions based on privilege mode presence.
  • Updated reset_value fields to UNDEFINED_LEGAL.
  • Removed the redundant WPRI field definitions and related text.

Please let me know if anything still needs adjustment!

Getting close.

The *INH fields should be definedBy the extension they control so that they appear to not be implemented if that extension isn't present.

For example

definedBy: Smcntrpmf
fields:
  SINH:
    definedBy: S
  VSINH:
    definedBy: H
