I have successfully patched Android 4.14 with mainline kernel 4.14. I have booted the kernel by merging omap2plus_defconfig, android-base.config and android-recommended-config config files and using the Debian rootfs. I see binder, ashmem in /dev. Is this enough to start porting full Android? I am doing this to get a good grip on Android porting so I am expecting a lot of errors.
