You have multiply issues with this kernel bump, some I'll write here, some inline.
The lack of commit message, explaining why You dropped some patches when transitioning from 5.4 to 5.10.
What also missing is: config refresh for cortexa53, cortexa72, and split of files because dts for ESPRESSObin got upstreamed.
For example how to do it better (I don't claim it's proper), You can check what I did two weeks ago in this tree: https://github.com/tmn505/openwrt/commits/mvebu-next
the commits lack commit messages (I had intention to add them later), but You'll get a gist of the changes, and that way You'll preserve changes between major kernel bumps.

Please copy patches from latest master, which have changed numbering according to target/linux/generic/PATCHES, it's easier to track backports.

I'm missing a chunk from this patch in init/main.c. If it doesn't apply cleanly, it doesn't mean You can delete it, please rework it.

All the PCI aardvark patches are included in 5.10 kernel no need to carry them.

This should have been changed in KERNEL_TESTING_PATCHVER, it's bit too early.
