Amlogic support on Alpine Linux

[yangxuan8282@gmail.com (He Yangxuan)]

Hi Neil,

The alpine kernel package `linux-amlogic` have been merged in alpine upstream:
https://github.com/alpinelinux/aports/commit/8dc0e43d5a410a6f173c14caaa625adaf45f11f4
The current kernel config only include arm64, maybe somebody can add armhf or armv7 
kernel config later.
And alpine u-boot package have add Odroid C2 support: 
https://github.com/alpinelinux/aports/commit/706b2721976b16d73274f23966f3f1a5735bf301#diff-bf45357b9515f24851da3b650e49829e 
will add Khadas Vim and Nanopi K2 in alpine u-boot package later. 
So after the alpine builder build the package, we will have basic support for amlogic
devices in alpine.
I'm thinking about package mali driver. Based on this mail: 
https://lists.infradead.org/pipermail/linux-amlogic/2017-June/004092.html
and Joseph's archlinuxarm package:
https://github.com/archlinuxarm/PKGBUILDs/blob/master/alarm/dkms-mali-utgard-meson
https://github.com/archlinuxarm/PKGBUILDs/blob/master/alarm/mali-utgard-meson-libgl
https://github.com/archlinuxarm/PKGBUILDs/tree/master/alarm/xf86-video-armsoc-meson
I have wrote the alpine APKBUILD for those three packages.
Most part is same as Joseph's work, but use your repositories as source. 
Actually I want to add wayland support and video acceleration.
In your this releases: https://github.com/superna9999/meson_gx_mali_450/releases/download/for-4.15/buildroot_openlinux_kernel_4.9_20180131_mali.tar.gz
there are several libMali.so (r7p0/m450/dummy,fbdev,wayland,r7p0/m450-X), I should use which one for wayland or video?
And besides xf86-video-armsoc-meson do we still need xf86-video-fbdev or xf86-video-fbturbo?
