[fedora-arm] support package for Helios4

Hi, as a fresh owner of the Helios4 NAS (batch 3) I've prepared a rpm with some bits to make the user experience better. It could be done with ansible playbook too, but I think a rpm is more convenient in this case. http://fedora.danny.cz/helios/bsp-helios4-1-1.fc31.noarch.rpm http://fedora.danny.cz/helios/bsp-helios4-1-1.fc31.src.rpm It simply packs - modules-load file to force load lm75 that's not loaded automagically - udev rules for the temperature sensors symlinks from Armbian - fancontrol config file using the symlinks - Requires: lm_sensors for fancontrol, i2c-tools for the OLED display shipped with batch 3 The fancontrol config is set for the single PWM control (j10) that's available in mainline (and Fedora) kernels. The source rpm contains also the Armbian's config with both fans, but this relies on the out-of-tree patch [1], which now requires rebasing. [1] https://raw.githubusercontent.com/armbian/build/master/patch/kernel/mvebu... to-do - ship a script controlling the OLED display - rebase the gpio/PWM patch and build some kernel with it Right now I'm running it with the bottom fan (uncontrolled) fan disconnected and it doesn't seem to be running too hot. But use this method on your own risk. Comments, contributions, etc are welcome :-) With regards, Dan
