No schemtics, no vendor source code right now thus no fip blobs to create mainline u-boot. Need to use chainloader to boot a mainline u-boot, then mainline kernel.
from pre-installed u-boot log, it's gxm_q201_v1 or its decendent.
add a simple dts and config to enable this Tv box. a simple doc for how to enable mainline uboot.

For first support, I think it would be simpler to copy the Q201 DT from Linux, rename meson-gxm-magicbox-m16s-u-boot.dtsi to meson-gxm-q201-u-boot.dtsi...

+Hacking notes for MagicBox M16S +=======================
+MagicBox M16S or MagicBox 3Pro is popular Tv box in China, which is +manufactured by Alibaba in 2016, with following specifications:
- Amlogic S912-H (S192 with dolby and DTS)
- 2GB DDR3 SDRAM
- 100M Ethernet
- HDMI 2.0 4K/60Hz display
- 1 x USB 2.0
- 16G eMMC
- Infrared receiver
- Marvel SD8897 WiFi module
- AV out
- Rest hole
- 5V2A power jack
+No schematics and source code available from vendor.
+U-Boot compilation +------------------
+.. code-block:: bash
- $ export CROSS_COMPILE=aarch64-none-elf-
- $ make magicbox-m16s_defconfig
- $ make
+Enable chainloader +--------------
+Due to no vendor source code, thus not able to create bootable u-boot image as other devices.
+thus only way to run mainline u-boot is chainloader.
+Step1: connect TTL to mainboard.
+Open metal cover, and you will see TTL test points show as below:
- G>--- <<-- gnd
--- <<-- Tx--- <<-- Rx--- <<-- pwr+Connect an USB TTL to these test points.
+Step2: enable chainloader.
+Connect USE TTL to you PC, and open it with any teminal tool, with configure: 115200n8
+Power on Tv box, and press `enter` on your keyboard. and then you get:
+.. code-block:: bash
- gxm_q201_v1#
+If not, power off, and redo this step.
+Type below u-boot command to console:
+.. code-block:: bash
- setenv OLDBOOTCMD "set_usb_boot 4;run storeboot"
- setenv USBBOOTCMD "usb start;if fatload usb 0 0x1000000 u-boot.bin; then go 0x1000000; fi;"
- setenv bootcmd "run USBBOOTCMD; run OLDBOOTCMD; run storeboot"
- saveenv
- sleep 1
- reboot
+If you reboot to pre-installed OS, there will be a very long boot time, just wait, it's not brick.
+Step2: prepare boot media
+Parition you Usb flash driver to Dos partition table, and first partition to 10M, format it to fat32.
+Copy u-boot.bin to first partition.
+Insert it to Tv box, it will automatically boot to mainline u-boot.
+Step3: optional boot script for sysboot
+If you want to use u-boot-menu to generate extlinux.conf to make a grub-like OS menu, +a simple boot script is needed. (assume your extlinux.conf is in 2nd partition)
+.. code-block::
- sysboot usb 0:2 any 0x1080000 /boot/extlinux/extlinux.conf
+# use: mkimage -A arm64 -T script -O linux -d boot.cmd boot.scr
+copy boot.scr to first partition, it will automatically load extlinux.conf and boot to OS.
+Status +----------- +Debian sid with kernel 5.19-rc4 +HDMI: OK, sound not test +WIFI: OK +eth: OK +BT: OK +IR: No decoder, keymap
+Issues: Due need to keep vendor u-boot, not able to use internal emmc.
Due to no power key, it will automatically poweron, even after poweroff.WIFI loss after reboot, need disconnect power to recover.
The doc & config looks fine, I'll do a full review with the Q201 DT.
When proper DT is upstreamed in Linux, then you will be able to add it to U-boot and switch to it.
