** - Software versions of OpenWrt/LEDE release, packages, etc.**
Alix 2d13 Geode LX platform

uname -a
Linux OpenWrt 5.4.24 #0 Sun Mar 15 20:38:05 2020 i586 GNU/Linux

At ~/openwrt/build_dir/target-i386_pentium_musl/linux-x86_geode/linux-5.4.24/.config we see:

Platform RTC drivers

CONFIG_RTC_DRV_CMOS is not set

** - Steps to reproduce**
hmm... git clone && make menuconfig
changed: GCC flags -march=geode -mmmx
&& make kernel_menuconfig
changed: CONFIG_MGEODE_LX=y
&& make world

All works fine but /dev/rtc0 is absent
