OK, so the last change from Jan here is:

    am654_sdhci: mmc fail to send stop cmd
    Hi all,
    on one device with one specific SD-card (possibly an aging one), I'm
    seeing frequent "mmc fail to send stop cmd" messages, followed by read
    errors when loading kernel and dtb. -ETIMEDOUT is returned by
    mmd_send_cmd. However, I can always resolve this by simply retrying the
    stop command like this:
    Hardware is our IOT2050, baseline is today's master (1c4b5038afcc) with
    board-enabling and a bunch of patches from your tree [1]. However,
    already 4d6da10ce611 exposes the problem.
    What could cause this?

Which is a generic MMC change, grows everyone by a little bit and lacks
both an S-o-B from the author and Reviewed-by of the MMC maintainer.
Please drop this patch.  Thanks!
