Aaron,
Sorry for late response.
Could you let me know it's a real case or review result? If it's a real case,
could you share us how to reproduce it?
In PCD_DATABASE_INIT of PcdDataBaseSignatureGuid.h, you can see below comments
//
// Padding is needed to keep necessary alignment
//
It means build tool should generate aligned pcd data and make all data access
work.
Please correct me if I misunderstand something.
Thanks
Feng

Subject: [edk2] [PATCH] MdeModulePkg: PcdPeim: Unaligned PcdSet in PEI for
architectures requiring alignment
On architectures that require aligned reads/writes, the PCD PEIM can cause a
misaligned access exception. This stems from the PcdPeim's SetWorker not using
the WriteUnalignedN functions from the BaseLib. The attached patch file
includes modifications to the PEIM that enforce unaligned access for calls to
PcdSet.
Best Regards,
Aaron
