Marble v1.4 Wishlist - Githubissues

[x] +12V and GND silkscreen marking on MTA-156 input
[x] reverse-polarity protection diode on +12V input
[x] BOM fixes, esp. heat sinks and I2C buffers
[x] smaller BOM?
[x] assembly house check for power-plane shorts
[x] Move test points to PCB connector (e.g. Tag-Connect TC2070; https://www.tag-connect.com/product/tc2070-nl-fp-footprint)
[x] DNI connectors for SPI and I2C busses (can be soldered on for debugging) (e.g. 609-3692-1-ND)
[x] Hardware flow control lines RTS/CTS from FT4232H DBUS to MMC
[x] Swap FPGA_INT and EXP_INT definitions on schematic to be consistent with v1.3
[x] DNI 0402 resistor between U21 pin 2 (clk) and Gnd. Allows recovery of FTDI chip by temporarily shorting EEPROM clk
