sorry for the delayed answer.

yes. We have some /etc and /root files in the kernel tree
which regularily need an update to exactly match the specific
kernel variant. Therefore the easiest thing was to pack them
with the modules which have the same constraint.
But we could think about splitting into modules.tgz and root.tgz

it is the same.

Oops. But that should be included... I have to check the build scripts.

That is something I have no idea about...

this is the first entry which reads the ADCs for voltage and current
and has a built-in formula in the script

Yes, it is the "battery type" ADC input. Which is not used on the GTA04
design, but other hardware. It could be used to measure a resistor built
into the battery to make the software know about small and big batteries.

this is the fuel gauge (bq27000) inside the battery, i.e. quite precise

this is our generic-adc-battery driver which tries to estimate the battery
fuel level like the formula in the script. But they differ for two reasons:
1. there is noise on the ADC signals so they may measure different voltage
2. the formula used by the generic-adc-battery driver is questionable

Ok! There may be some flag missing for tar.

I'll check - maybe this load balancing is newer than when we started
to have makesd :)
Thanks for testing and reviewing!
