On some Arm platforms the boot firmware volume passed in the HOB by the secure world firmware (TF-A) is never freed and is always mapped as read-only. On such platforms the heap memory can be saved by disabling the shadow copy of the boot firmware volume. This is useful as on some platforms the amount of memory available is limited. Therefore, introduce a PCD PcdShadowBfv that platforms can configure to disable the shadow boot FV. This PCD is set to TRUE by default. Signed-off-by: Levi Yun <[email protected]>
