     36  * The exynos can boot from its iROM or from an external Nand memory. Since
     37  * these are normally hardly used they are excluded from the normal register
     38  * space here.

     40  * XXX What about the audio subsystem region. Where are the docs?
     41  *
     42  * EXYNOS_CORE_PBASE points to the main SFR region.
