  24 * This table is only for optimization. Since ioremap() could always share
  25 * the same mapping if it's defined as static IO mapping.
  26 *
  27 * Without this table, system could also work. The cost is some virtual address
  28 * spaces wasted since ioremap() may be called multi times for the same
  29 * IO space.
