So I have been having some fun and success getting Slitaz (core64) booting UEFI on my Acer laptop. Now I'm struggling with how to get the SDcard reader working. I've installed linux-mmc and tried to install mmc_block module, but the module does not exist in the modules supplied with my version.
# uname -a
Linux slitaz 3.16.55-slitaz64 #2 SMP Sat Aug 1 11:47:34 UTC 2020 x86_64 GNU/Linux
# ls /lib/modules
3.16.55-slitaz64 3.18.129-gnu-slitaz
modprobe doesn't find any mmc_block module in 3.16.55-slitaz64 but it does exist in
3.18.129-gnu-slitaz
