The pumpkin board is made by Gossamer Engineering and is using a MediaTek SoC. The board currently comes in two available version: MT8516 SoC and MT8167 SoC. The board provides the following IOs: eMMC, NAND, SD card, USB type-A, Ethernet, Wi-Fi, Bluetooth, Audio (jack out, 2 PDM port, 1 analog in), serial over USB, and an expansion header. Additionally there is a HDMI port, DSI port, and camera port only on the MT8167 version of the board. The board can be powered by battery and/or via a USB Type-C port and is using a PMIC MT6392. The eMMC and NAND are sharing pins and cannot be used together. This commit is adding the basic boot support for the Pumpkin MT8516 board on the eMMC.
