| * |
| * 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>). |
