24 | * This is rather complicated for humans and ugly to verify, but for a machine |
25 | * it's OK. Still more as it is usually only applied to constants. The upsides |
26 | * on using this approach are: |
27 | * |
28 | * - same mapping on all i.MX machines |
29 | * - works for assembler, too |
30 | * - no need to nurture #defines for virtual addresses |
31 | * |
32 | * The downside it, it's hard to verify (but I have a script for that). |
33 | * |
34 | * Obviously this needs to be injective for each SoC. In general it maps the |
35 | * whole address space to [0xf4000000, 0xf5ffffff]. So [0xf6000000,0xfeffffff] |
36 | * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there). |
37 | * |
38 | * It applies the following mappings for the different SoCs: |
