Add decoupling/stitching capacitors to the 5V_P, 3V3_P, and 1V8_P rails which will be spread through the respective power planes (not necessarily having to be near chips)

Add preliminary Bill-of-Materials, fill in more missing component information such as inductor selection for the 3V3(_P) rail

Most critical components should now be getting ordered.

Add decoupling capacitors near the WLAN+BT M.2 Key E socket, assign the tantalum capacitors their various footprints, find suitable 220uF tantalum bulk capacitors for the M.2 modules which are rated to 10V

Need to figure out if the load switch IC (AP22800) that derives 3V3_P is fine with having the large output capacitance (no unwanted reverse current).

Begin GNSS schematic using MAX-M8 module

Since UART2 isn't brought out then will either need to use UART1 (debug) with jumpers or the module's I2C interface.

Resolve merge conflict after pulling recent commit, now can no longer use SSH (since Gogs is getting abandoned?).

Add camera/CSI circuit, include second switch that is part of the audio+camera DPDT for killing both simultaneously, level shifters used for camera's I/O that requires it, footprints for a 1.8V LDO which may be used by DVDD will be included

External DVDD (1.8V LDO) needs to be tested if it's needed (datasheet says an internal DVDD can be used, as is the case with Boundary Devices' OV5640 camera).
