+/*
+ * 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
