616 * TNETV107X platforms do not use the static mappings from Davinci
617 * IO_PHYS/IO_VIRT. This SOC's interesting MMRs are at different addresses,
618 * and changing IO_PHYS would break away from existing Davinci SOCs.
619 *
620 * The primary impact of the current model is that IO_ADDRESS() is not to be
621 * used to map registers on TNETV107X.
622 *
623 * 1. The first chunk is for INTC: This needs to be mapped in via iotable
624 * because ioremap() does not seem to be operational at the time when
625 * irqs are initialized. Without this, consistent dma init bombs.
626 *
627 * 2. The second chunk maps in register areas that need to be populated into
628 * davinci_soc_info. Note that alignment restrictions come into play if
629 * low-level debug is enabled (see note in <mach/tnetv107x.h>).
