^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * This is rather complicated for humans and ugly to verify, but for a machine
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * it's OK. Still more as it is usually only applied to constants. The upsides
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * on using this approach are:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) * - same mapping on all i.MX machines
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * - works for assembler, too
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * - no need to nurture #defines for virtual addresses
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * The downside it, it's hard to verify (but I have a script for that).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) * Obviously this needs to be injective for each SoC. In general it maps the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) * whole address space to [0xf4000000, 0xf5ffffff]. So [0xf6000000,0xfeffffff]
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there).
