/*
|
|
* 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:
