Hi All,

Sorry for the [edk2-platforms] prefix attached to the subject line. This is 
edk2 patch series. Will fix the prefix in next version.

- Omkar.

> Changes since v2:
> - Addressed the comments given by Sami.
> - Added Readme file with all cover letter information.
> - Rebased to the latest upstream code.
>
> Hardware Error Source Table (HEST)[1] and Software Delegated Exception
> Interface (SDEI)[2] ACPI tables are used to acomplish firmware first error
> handling.This patch series introduces a framework to build and install the
> HEST ACPI table dynamically.
>
> The following figure illustrates the possible usage of the dyanamic generation
> of HEST ACPI table.

>   These two drivers together retrieve all possible error source descriptors of
>   type GHESv2 from the MM drivers implementing HEST Error Source
> Descriptor
