Re: [edk2-devel] [staging/dynamictables-reorg PATCH 00/15] Prepare libraries to support other archs

["Sami Mujawar" <sami.mujawar@arm.com>]

Hi Sunil,

I think we can look into that. My initial thoughts are that this can be solved using a Pcd. However, we need a bit of investigation.
Is it ok if we address that in a separate patch?

Regards,

Sami Mujawar

Hi Pierre, Sami,


Thanks a lot again for this work!.


The series looks good to me as well. I agree with Sami's suggestions.


However, I have a request for an additional change. The common ACPI
tables still use ARMH/ARMLTD as the CREATOR_ID/OEM_ID. Can they be made
architecture specific?
