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