Getting your kernel and u-boot patches upstream is something I support.

I suggest you rebase your tree on the latest upstream (v4.9), and get
it to boot with a simple userspace.

Once you have that working then I suggest we get the essential drivers
and architecture support upstream. This list might include serial,
irq, ethernet, and device tree. The code will require rework to meet
upstream kernel standards. You will also need to be come familiar with
the tools used by the upstream kernel; git, patches and mailing lists.
Read this documentation:

Alistair (on cc) is the upstream maintainer for the PPC SoC the FSP2
is based on, so your patches must go through his process before being
merged by the PowerPC maintainer, and finally hitting Linus' tree.

The u-boot work will be a similar process.

Cheers,

Joel
