NACK.
For starters, if this were an actual fix, it should have a Fixes header.
Don't do random changes in a single patch and call it a "fix". I don't
see what changing the cell size has to do with smp, nor adding L2 cache.
The latter could be a patch of its own, after fixes are applied (to
avoid conflicts when backporting that fix to older branches). A cell
size of two used to be perfectly valid, please checking the DT binding.

Sorry for that, got it.
you just update its TF-A firmware and use the standard PSCI interface
for Linux? If not, then you should add your workaround to your
module's/board's .dts(i) instead of the SoC's .dtsi.
Yes, the vendor does not seem to support this for now. I think for now
the best thing to do is to leave the workaround on the module's .dtsi.
Thank you for the tips.
Thanks,
