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:
