Hi Okash,

Could you please let us know the real use case/requirement where you want MTE to be available at EL3?

Thanks,
Manish Badarkhe

Subject: [TF-A] Status of MTE for bl31

Hi,

I wanted to check the status of MTE support for bl31 itself. It seems
like the support was added [1] for clang and armclang but I couldn't
find the memory attribute to map pages as tag checked [2]. Is there
something I missed?

Thanks,
Okash
