T95 is a most commonly known for being a box with a pre-installed malware. It uses Allwinner H616 and comes with eMMC and DDR3 memory. This device comes with two versions - one with AXP305 PMIC and another with AXP313 PMIC. The AXP313 version comes with Secure Boot enabled and locked bootloader, so the u-boot has to be built with TOC0. DRAM settings are taken from Allwinner's boot0 for this box.
