[Update: MT8173 processor has now been announced, and it’s using Cortex A72 and A53 instead of A57/A53, as initially shown in the Linux kernel source code] Mediatek is not exactly known to compliant with open source licences, or be involved with the open source community. But the company is certainly going into the right direction with their cooperation with Google leading to source code release for Android One smartphones, and the recently launched Mediatek Labs for community projects, starting with LinkIt One IoT platform. Mediatek is also regularly submitting code to the Linux ARM Kernel mailing list, and yesterday code was submitted for Mediatek MT8173 SoC, a 64-bit ARMv8 processor with two Cortex 53 and two Cortex 57 cores in big.LITTLE configuration. As far as I know, it could be the first Mediatek SoC with “big” Cortex A57 cores. Code snippet from mt8173.dtsi related to CPU cores:
