/*
* 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:
*
* mx1:
* IO 0x00200000+0x100000 -> 0xf4000000+0x100000
