This adds a way to handle physical events like keypad slide switch,
screen lock, camera lid, and others. This uses acpid from busybox (I was
wrong about the real acpid package), and anl acpi.map file to map events
to 'scripts'. The scripts are symlinked to /etc/acpi/handler.sh,
automatically by the new post-install script, where
they are handled based on which script was called. This allows for
easily adding whatever is necessary for #178.
If this PR is merged, I will create a new wiki page detailing how others
can use this framework on other devices.
There's an issue with Busybox's acpid, where it is unable to detect new
devices added after the daemon loads. This is the case on the N900,
where openrc starts acpid well before the kernel is done modprobing
drivers (e.g. gpio_keys), so it's necessary to restart the acpid daemon
after some time to 'load' the new devices.
This properly exports the uImage kernel, which is used by u-boot, when
running 'flasher export'. Note the change to the uImage name to follow
the pattern "uImage-$flavor", which in the case of the RX 51 is
"uImage-nokia-rx51".
The uInitrd filename is appended with 'flavor' so, for example, with the
rx-51 the generated file is named 'uInitrd-nokia-rx51'. This corrects
the rx51's u-boot script to account for this change in filename.
This removes the call to `firmware_install` in the APKGBUILD for
linux-nokia-rx51, and adds the `linux-firmware` package as a dependency
for device-nokia-rx51.
There are two immediate benefits for this:
1) wifi now works
2) the FM radio device was causing the boot to take ~2 minutes longer
than it should, now that the firmware is present there's no delay in
initializing this device
