41 * Set up static device mappings.  This is hand-optimized platform-specific
42 * config data which covers most of the common on-chip devices with a few 1MB
43 * section mappings.
44 *
45 * Notably missing are entries for GPU, IPU, in general anything video related.
46 *
47 * Note that for imx this is called from initarm_lastaddr() so that the lowest
48 * kva address used for static device mapping can be known at that point.
