As mentioned in #151, the Raspberry Pi Zero doesn't have an ethernet
port, so this makes it quite complicated to connect to the device from
a fresh install, because wifi/bluetooth/serial/... are not configured.
With this new package, the device starts with the microUSB configured as
ethernet and the dhcpd is running on the RPI, so you can simply connect
it to a computer and connect with SSH in order to configure it.
Use the device's architecture instead of noarch. Because the device
packages should never be built for other architectures, even if all
depends can be built for other arches as well.
This simplifies package building as part of the new build
infrastructure effort.
pmbootstrap has also been changed to output this by default in
aportgen.
Alpine's firmware packages have been updated to include the latest
raspberry pi firmware. This commit adjusts our aports.
Details:
* remove obsolete `aports/temp/linux-firmware`
* `firmware/firmware-pi-bluetooth`: rename to `device/bluetooth-raspberry-pi`
and remove firmware files (they are part of Alpine's `linux-firmware` now)
* `device-raspberry-pi`: depend on `bluetooth-raspberry-pi`
* `device-raspberry-pi`: note that Alpine's kernels depend non free firmware
* `device-raspberry-pi`: remove non free firmware subpackage
