32 | /* |
33 | * This is rather complicated for humans and ugly to verify, but for a machine | |
34 | * it's OK. Still more as it is usually only applied to constants. The upsides | |
35 | * on using this approach are: | |
36 | * | |
37 | * - same mapping on all i.MX machines | |
38 | * - works for assembler, too | |
39 | * - no need to nurture #defines for virtual addresses | |
40 | * | |
41 | * The downside it, it's hard to verify (but I have a script for that). | |
42 | * | |
43 | * Obviously this needs to be injective for each SoC. In general it maps the | |
44 | * whole address space to [0xf4000000, 0xf5ffffff]. So [0xf6000000,0xfeffffff] | |
45 | * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there). | |
46 | * | |
47 | * It applies the following mappings for the different SoCs: | |
