[Buildroot] [PATCH 1/2] board/licheepi_zero: move board files to their own directory

[Francois Dugast]

Group files for board licheepi_zero under a new directory. This is
to prepare for a new board also coming to the licheepi directory.

[Buildroot] [PATCH 2/2] board/licheepi/licheepi_nano: new board

[Francois Dugast]

Add support for the LicheePi Nano with:
- U-Boot 2023.04
- Linux current latest version

Board homepage: https://linux-sunxi.org/LicheePi_Nano

linux.fragment is required to disable some features in order
to keep the kernel size small, otherwise the board does not
boot due to limited memory. See note in readme.txt.

+Intro
+=====
+
+This directory contains a buildroot configuration for building a
+LicheePi Nano image which can be flashed into the board.
+
+This frees the MMC port which can be used for an additional SD
+card of for a WiFi adapter.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+  $ make licheepi_nano_defconfig
+
+Build the rootfs
+----------------
+
+Note: you will need to have access to the network, since Buildroot
+will download the packages' sources.
+
+You may now build your rootfs with:
+
+  $ make
+
+(This may take a while, consider getting yourself a coffee ;-) )
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- flash.bin
+    +-- rootfs.jffs2
+    +-- rootfs.tar
+    +-- suniv-f1c100s-licheepi-nano.dtb
+    +-- u-boot.bin
+    +-- u-boot-sunxi-with-spl.bin
+    `-- zImage
+
+How to flash
+============
+
+Once the build process is finished you will have an image called
+"flash.bin" in the output/images/ directory. It contains the
+bootloader, the device tree, the kernel and the root file system.
+
+The device can be flashed when it is in special mode called "FEL
+mode". There are multiple ways to enter this mode described here:
+https://linux-sunxi.org/FEL#Entering_FEL_mode
+
+One way is to write one file from sunxi-tools to a SD card with:
+
+  $ sudo dd if=./output/build/host-sunxi-tools-*/bin/fel-sdboot.sunxi of=/dev/sdX bs=1024 seek=8
+
+Once the SD card is burned, insert it into your LicheePi Nano board,
+and plug the USB cable. A new USB device should be visible with
+lsusb:
+
+  1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode
+
+The image can be flashed with:
+
+  $ sudo ./output/host/bin/sunxi-fel -p spiflash-write 0 output/images/flash.bin
+
+Once this completes, remove the SD card and power the board. Your
+new system should come up now and start a console on the UART0
+serial port.
+
+Note
+====
+
+Some standard kernel features are disabled using the fragment in
+order to reduce the size. They can be enabled again if other
+features are disabled instead.
+
+For U-Boot, the upstream repository is preferred and the system
+boots, but loading the image from the flash takes a long time. It
+is much faster when using the branch "licheepi-nano-v2020.01" of
+this fork:

Licheepi-zero is a board by Sipeed, the manufacturer, and we already had
a subdir for them, so I moved the board files there rather than
introduce the board/licheepi/ sub-dir.

Applied to master, thanks.

We do not leave the kernel version to the l;atest one, because we want
to have known-working defconfigs, and so bumping the kernel (and
bootloader) version should be explicit (and tested) rather than follow
whatever the latest kernel version is.

So I pinned the version to kernel 6.5.9, which is the current latest
known to Biuldroot (so, presumably what you tested with).

> Board homepage: https://linux-sunxi.org/LicheePi_Nano

I added the true home page on the manufacturer website, and kept the
linux-sunxi wiki URL too.

Of course, like for licheepi_zero, I moved that to the sipeed sub-dir.

And as for licheepi_zero, I renamed the defconfig to start with sipeed,
like all the other sipeed boards.

Oops, I forgot to rename licheepi_zero, so I've pushed a fixup commit...

Applied to master with the above changes, thanks.

Yann E. MORIN.

Could you rename the folder to licheepi-zero instead of licheepi_zero?

I would have done it myself while applying if there were no other
issues with the patch series, but I have comments on PATCH 2/2.

Best regards,

I see you actually sent a newer version, which has been merged, and
this earlier version had not been marked as Superseded in our patch
tracking system. You can therefore ignore my previous e-mail.

Best regards,

Thomas
