r436 full sysmem PTE aperture/VOL matrix: gsp_phys_rmcall_pte_coh becomes a 4-mode selector (0=0xf aperture3+VOL historical, 1=0xd aperture2+VOL r431, 2=0x5 aperture2 non-volatile, 3=0x7 aperture3 non-volatile) applied consistently to the leaf PTE and the single PDE (bit0 = IS_PDE there), so the r431 finding (aperture 2 with VOL still 1 is a pair the reference RM never emits) can be A/B'd against the consistent encodings
