Hi @xypron and @bertrand-marquis, |
source/chapter3-secureworld.rst
Outdated
| On AArch64 platforms, when privileged or secure firmware implements the Platform | ||
| Fault Detection Interface (PFDI), it must be compliant with the requirements | ||
| defined in [PFDI]_ § 5 Compliance Requirements, and it must therefore respond | ||
| with version 1.0 to a `PFDI_VERSION` request. [#PFDINote]_ |

I think you are repeating the spec content which is not very useful.
If you do link to PFDI 1.0 then saying that it must be compliant to it is enough, saying that 1.0 must be returned is repeating things

Hi @bertrand-marquis, thanks for the review.
It seems that I am in fact struggling to find the right wording.
What I am trying to obtain is a requirement on the firmware in term of minimal PFDI version implemented, and somewhat decoupled from the version of the PFDI specification we reference.
I will do another try.

This is now reworded; let me please know how you like latest version.
