Hi Eric, First of all, I am EXTREMELY sorry for my long overdue response.. I just wanted to bring up that piece of HW so as to offload crypto tasks from the CPU, but it ended up being slower (which I suspect is due to bw scaling not being implemented, but I might be wrong, maybe A53+crypto is just superior..) The goal is to have the phone run Mainline Linux *at least* at functional parity with the BSP kernel. Both ICE and CE support are welcome. Thanks for your interest and the patches you sent. There is more sdm630 (and not only, keep watching :D) work coming. I suppose you managed to boot your Xperia by now, but if you had issues, you should try out my v5.10-rc3 branch from the repo you linked with the supplied ninges_defconfig. Then you append the DTB to Image.gz and create an Android boot image (or put Image.gz+dtb into an existing one with abootimg -u boot.img -k Image.gz+dtb) and the phone should boot. Thanks once again for your interest and apologies for the time it took.. Konrad
