+ * If the firmware is compiled with static addresses, then @da should specify

+ * Some remote processors needs to know the allocated physical address
+ * even if they do use an iommu. This is needed, e.g., if they control
+ * hardware accelerators which access the physical memory directly (this
+ * is the case with OMAP4 for instance). In that case, the host will
+ * overwrite @pa with the dynamically allocated physical address.
+ * Generally we don't want to expose physical addresses if we don't have to
+ * (remote processors are generally _not_ trusted), so we might want to
+ * change this to happen _only_ when explicitly required by the hardware.
