![]() Make the default value for MTPME always be 1 to preserve the reset behaviour on newer revisions and on older revisions where the bit is RES0 it doesn't matter. Before its introduction MDCR_EL3.MTPME was RES0. Upon its introduction the field resets to 1, making the MTPMU architecturally "enabled". As such, the logical action on TF-A's part is to "disable" it, which led to the introduction of DISABLE_MTPMU. This hinges on the assumption that MDCR_EL3.MTPME will always be 1 unless the above flag is set. Unfortunately this is not the case, as the reset value is overwritten at reset with a macro that sets this bit to 0.
