* 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>).
