I do not oppose the addition of a new platform, even though, like
Jiaxun, I would prefer to avoid duplicating code. The only thing
preventing the use of the same kernel for EyeQ5 and other platforms is
the starting address.
there shouldn't be code duplication.
My rough idea would be something like

so everyboady needing these parts of a generic kernel is able
to take it.
Therefore, if it were possible to have a relocatable kernel, this
issue would disappear.
yes. There is support for relocatable kernel, so what are we missing
there ?
It does not handle 64 bit relocations currently.
I tried to look into it and it's not a easy fix.
Thanks
