+/*
+ * 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
