Banana Pi P2 Zero is H2+-based board by Sinovoip internally
similar to Banana Pi M2 Zero.

It features:
- Allwinner H2+, Quad-core Cortex-A7
- 512MB DDR3 SDRAM
- 8G eMMC flash
- MicroSD card slot
- 100M LAN
- WiFi (AP6212) & Bluetooth onboard (SDIO + UART)
- Micro USB OTG port
- Micro USB connector (power only)
- Mini HDMI
- 40 PIN GPIO includes UART, SPI, I2C, IO etc.
- GPIO-connected key and LED
- CSI connector
- IEEE 802.3af PoE standard PoE module support (optional)

This adds support for v1.1 revision. There was also v1.0 available
which has different SDcard CD polarity and Ethernet port LEDs
disconnected in layout.

Please send this to the proper recipients (get_maintainers.pl will help)

That's what I used. I've also greped Documentation for get_maintainer.pl and read various bits there. And looking at headers of other patches I'm still not sure.

Am I supposed to send the patch to all people in the script output and just Cc the list?

Yes, the script is here to list all the recipients you need to send that
patch to
