The RAP TA contains tests used to verify if RAP(Register Access Policy), or otherwise known as Security Policy is applied correctly by PSP BL&TOS. The RAP test is a measure to ensure that we reduce the avenue of complexity and mistakes when dealing with RAP in post-si execution, where debugging failures related to RAP is quite difficult and expensive. v2: add introduction for RAP TA Signed-off-by: Wenhui Sheng <Wenhui.Sheng@amd.com> Reviewed-by: Guchun Chen <Guchun.Chen@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
