Ipfire running on Clearfog Base and clearfog Pro boards, based on Armada A388 SoC (Arm v7) is good for small networks, but is missing the RTC interface as the kernel module for Armada 38x RTC is not set in the kernel config. Please include as a loadable module so system time can be persisted through reboots.
The config is CONFIG_RTC_DRV_ARMADA38X
patch submitted to make the Armada 38X RTC module loadable.
The module has been added only to the 64 bit aarch64 architecture as the 32 bit armv6l architecture is no longer being supported after Core Update 173
