| /* |
| * This is rather complicated for humans and ugly to verify, but for a machine |
| * it's OK. Still more as it is usually only applied to constants. The upsides |
| * on using this approach are: |
| * |
| * - same mapping on all i.MX machines |
| * - works for assembler, too |
| * - no need to nurture #defines for virtual addresses |
| * |
| * The downside it, it's hard to verify (but I have a script for that). |
| * |
| * Obviously this needs to be injective for each SoC. In general it maps the |
| * whole address space to [0xf4000000, 0xf5ffffff]. So [0xf6000000,0xfeffffff] |
| * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there). |
| * |
| * It applies the following mappings for the different SoCs: |
