uGoos Am6 Plus: Boot, DTB, wifi

[S8D]

Hello MFC, first of all I would like to thank you for spending a considerable amount of time integrating hardware devices into img files so that they work quite well on many devices, including the device I am using: uGoos Am6 Plus, however, I have some problems when running the IMG file on my uGoos Am6 Plus, please help me fix the error.

1. For the boot configuration file, I used beelinkgtking's dtb file because they use the same chip, and the configuration is almost the same so it works quite well, but cannot use wifi because uGoos Am6 Plus uses the AMPAK AP6359S chip, hopefully MFC will Integrate this driver or build this driver package (bash scripts are also fine) to make installation easier. Thank you

   The DTB file identifies enough hardware and drivers ok from the link below: https://mirror.fkardame.com/Linux/Images/Ugoos/Am6%20Plus/Manjaro-ARM-xfce-am6-plus-20210201.img.xz

2. Next, in version 6.1.57, there is support for specifying the Root partition for emmc/sdcard, so it is very convenient when I uncompress img into emmc and run debian/ubuntu directly from emmc after booting from sdcard/usb otg, because My device cannot boot directly from emmc. The problem is that the latest kernel that MFC supports no longer supports booting from the specified partition. Due to the error of not recognizing the sdcard, I have to use an older kernel version. Hopefully MFC will fix this error.

3. Finally, the scripts boot/install into emmc. I see that there is only one script installed into ophub's emmc that works well. It can independently boot both the root partition and boot from emmc, so it's very convenient. I hope MFC can extract this part of the scripts to support installing ubuntu/ debian into emmc more effectively. Thank you.
