Hi Neil. We can be enable boot partition using mmc-utils. See this address. https://git.kernel.org/cgit/linux/kernel/git/cjb/mmc-utils.git/commit/?id=7bd1320b2cb38f040ab5cf017d17e283496690bf
So, I don't think this patch is useful. If you consider to be disable boot partition, you can try to update mmc-utils base on the address I shared.
