Hi Mugunthan,

Based on the OF_TRANSLATE Kconfig description, this is required
only on platforms with complex "ranges" in the DT nodes. For
simpler platforms using SIMPLE_BUS should be sufficient. Since
this a set to default y, simple bus is never used in any
platform. So make the default value as "n" and enable
OF_TRANSLATE only on required platform.
How do you know it is not used? This is surprising because Stefan
presumably added it to fix something.
I assume Mugunthan meant, that simple bus is never used. This
is not quite correct, as its at least used per default in the
SPL (because of size reasons).
And yes, this translation via fdt_translate_address() is needed.
At least for some platforms, like mvebu & nios2 (IIRC). Stephen
also made some quite striking comments about this a few weeks
ago. And I really think that we should make use of this function
per default. Platforms that know for sure that they don't need
this functionality can always disable it selectively.
Mugunthan, why do you want to disable this functionality? Does
it cause problems on your platform? If yes, which ones?
Thanks,
Stefan
