FWIW I've done a debian package branch: https://github.com/wens/MaxMind-DB-Reader-php/tree/debian It only contains the C extension, not the PHP files. I might setup a personal PPA to host it.
This is a known issue. Please use GCC 6 or later.
Booting non-secure with mainline U-boot is only supported for mainline Linux. If you want to use Allwinner's kernel and boot non-secure, I suggest you use their bootloaders as well.
Is the UART out of reset?
You are using the mainline kernel, but following the legacy kernel howto. Please see http://linux-sunxi.org/Mainline_Kernel_Howto first.
What boot commands are you now using? (What is in boot.scr?) Specifically, what is your bootargs? You could also try a newer version of U-Boot.
Seems right, though there shouldn't be braces ( "[" "]" ). That is there to indicate that "earlyprintk" is optional.
