Here is a patch series trying to implement the conclusions about accessing the SD divider table, coming from this discussion [1]. Patch 1 is a tiny, yet seperate cleanup. Patch 2 is the bulk of the work doing the checks only when needed. I think the code looks much better now.
I tested this on a Salvator-X (R-Car M3-W) with highspeed and UHS SD cards. I could access them and checksum files. I also did not notice any performance regressions. There are also no WARNings in the boot log. Please let me know if this is what you had in mind and if you can think of other ways of testing this change.
