[Buildroot] [PATCH v2] board: add Orangepi Zero Plus support

[Buildroot] [PATCH v2] board: add Orangepi Zero Plus support

[Marcin Niestroj]

Add initial support for Orangepi Zero Plus board:
- U-Boot 2020.10
- Linux 5.7.19
- Default packages from buildroot

This patch is based on Orangepi Zero Plus2 board support, so genimage
configuration and description is copy pasted. One difference is that
newer Linux and U-Boot are selected. Another difference is Ethernet
support (Plus) instead of WiFi (Plus2).

changes v1 -> v2:
 * rebase on Buildroot master
 * bump U-Boot from 2020.04 to 2020.10
 * bump Linux from 5.6.6 to 5.7.19

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Orangepi Zero Plus. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Orangepi Zero Plus link:
+http://www.orangepi.org/OrangePiZeroPlus/
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make orangepi_zero_plus_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sudo sync
+
+Insert the micro SDcard in your Orangepi Zero Plus and power it up. The console
+is on the serial line, 115200 8N1.

Committed, thanks.

I wonder if we could combine some of all these orangepi defconfigs and
create a single build that works on multiple boards rather than
maintaining all these almost similar files?

Both orangepi_zero_plus and orangepi_zero_plus2 use the same
processor. It seems like a good idea to unify them. Maybe next time
someone will want to bump orangepi_zero_plus2 it will be a good occasion
to test both boards with same Linux + U-Boot versions.
