[edk2-devel] [PATCH v5 0/1] MdeModulePkg/AcpiTableDxe: Prefer xDSDT over DSDT when installing tables

["Dhaval Sharma" <dhaval@rivosinc.com>]

As per ACPI Spec 6.5+ Table 5-9 if xDSDT is available,
it should be used first. Handle required flow when xDSDT
is absent or present.

Test: Tested on RISCV64 Qemu platform with xDSDT and booted to
linux kernel.

Notes:

    - If DSDT is not found, throw error and continue to build other tables with
      an error log
    v4:
    - Fix typos and commit message adding more clarity to patch subject
    v3:
    - Added description of ACPI spec clarification based on which this patch is created
    - Optimizing if-else flow
