Subject: [PATCH v1 0/2] Support MM based variable services in PEI for ARM
Date: Thu,  8 Jun 2023 13:44:32 -0700	[thread overview]
Message-ID: <20230608204434.2325-1-kuqin12@gmail.com> (raw)

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4464

As of today, there has been a void in the variable service in PEI phase
on ARM systems that support PEI phase and standalone MM hosted variable
service.

This change adds the support through:
1. Add MM communication services in PEI phase for ARM platforms. This
module is based on SMC calls to standalone MM environments, similar to
"ArmPkg/Drivers/MmCommunicationDxe".

2. A service module that installs `gEfiPeiReadOnlyVariable2PpiGuid` based
on step 1. Note that this driver will not have special dependency on ARM
specific code, thus will be ideally added to MdeModulePkg.

Patch v1 branch: https://github.com/kuqin12/edk2/tree/arm_var_pei_v1
