[Buildroot] [PATCH 1/3] configs/orangepi_pc2: add board support

[Javad Rahimi]

This patch adds requried configuration for OrangePI PC2 board.
It was supproted before, however due to problems in
building Arm Trusted PLatform, it was removed in
 commit "eeede611f81d8f83b72e4a6671cd7d1e46b266b0"

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Orangepi PC2. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Orangepi PC2 link:
+http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-PC-2.html
+
+Sunxi Wiki link:
+https://linux-sunxi.org/Xunlong_Orange_Pi_PC_2
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make orangepi_pc2_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 PC2 and power it up. The console
+is on the serial line, 115200 8N1.

Sorry for the long delay in getting back to you. I have applied your
patch series, but after squashing the 3 patches together in one commit.
Splitting it into 3 didn't make sense in this case.

However, could you work on updating the version of the components in
the defconfig? Building Linux 5.16, TF-A 2.5 and U-Boot 2022.01 is
quite old. Could you submit a followed-up that updates this defconfig
to newer Linux, newer TF-A and newer U-Boot? Please make sure to base
your patch on our "next" branch, as I merged your contribution into
this "next" branch.

Thanks a lot!

Sure, I have updated the kernel, TF-A and Uboot.
However, I have faced a problem with "/dev" management after upgrading
the packages. When it is in "Dynamic using devtmpfs only" mode, no
kernel module is loaded after boot. But in "Dynamic using devtmpfs +
mdev" everything works fine. Can I put it in this mode?

Well, this is normal, devtmpfs is only a virtual filesystem that
creates entries in /dev. It is not involved in automatic module
loading. If you want automatic module loading, you need either mdev or
udev/eudev. And it's indeed fine to enable mdev in defconfigs that need
it.

Best regards,

Thomas

Thanks a lot,
 I have added it to the defconfig and committed the patches.
