Why does this keep coming up?
Arnd
We need this memory region because boot address for exynos5410 located
here, same as for 5250.
Is there really no way to map this region dynamically in the entity
(driver, source file, whatever) that actually uses it? The goal is to
get rid of all the static mappings entirely, so adding new one makes us
further from it.
Best regards,
Tomasz
