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:
