The NVIDIA P3310 is a processor module used in several reference designs
that features a Tegra186 SoC, 8 GiB of LPDDR4 RAM, 32 GiB eMMC and other
essentials such as ethernet, WiFi and a PMIC. It is typically connected
to an I/O board (such as the P2597) that provides the connecters needed
to hook it up to the outside world.

I don't think we need 'console' in the bootargs anymore because
stdout-path is enough (even for early console).
