The MESON_AO_RPROC_SRAM_USABLE_BITS macro is used like this: if (priv->sram_pa & ~MESON_AO_RPROC_SRAM_USABLE_BITS) { dev_err(dev, "SRAM address contains unusable bits\n"); The problem is that "->sram_pa" is type phys_addr_t which is potentially 64 bits. That means the MESON_AO_RPROC_SRAM_USABLE_BITS macro needs to be a 64 bit type as well to ensure that high 32 bits are cleared.
