You've confused me with Markuss Broks <markuss.broks@gmail.com>.

He was the one who brought up A8X. I brought up A8 (in particular

iPhone 6).

For A7-A8X, the tags are from Konrad's linux fork from two years ago,
though your tags in particular may no longer apply since as you can
see, all memory related things are now /* To be filled by loader */.
