> Subject: [`edk2-devel][PATCH 0/8] Add SMM variable support for UEFI payload
>
> From: Guo Dong <guo.dong@intel.com>
>
> https://bugzilla.tianocore.org/show_bug.cgi?id=3084
>
> Currently UEFI payload uses emulated variable driver. So it could
> not support secureboot and measured boot since both need NV variable
> support.
>
> EDKII already has SMM modules and variable modules. And modern Intel
> platform supports SPI flash hardware sequence to operate flash. So it
> is possible to have a common SPI module for Intel platforms.
>
> This patch enhances UEFI payload to support SMM variable with a
> common SPI library for Intel platforms. To avoid impact existing
> usage, all the new modules are included under SMM_ENABLE and
> VARIABLE_SUPPORT and by default SMM variable is not be enabled.
>
> SMM variable could be enabled only when UNIVERSAL_PAYLOAD is set
> since non-universal payload need update ParseLib to provide SMM
> variable related infromation which is not in the plan.
