[Buildroot] [PATCH 0/9] Add RISC-V NOMMU and Canaan K210 SoC support

[Buildroot] [PATCH 0/9] Add RISC-V NOMMU and Canaan K210 SoC support

[Damien Le Moal]

This series adds support for building RISC-V NOMMU kernel bootable
images for boards using the Cannan Kendryte K210 SoC.

The first patch makes MMU builds optional for RISC-V. The second patch
enables RV64 support in elf2flt (patch sent to uclinux-dev). The third
patch changes the base name of the toolchain to avoid build errors.

The following 5 patches add default build configuration files for
various boards: MAIX-bit, MAIX-go, MAIX-dock (Dan Dock) and MAIXDUINO
from Sipeed and the Canaan KD233 development board.

Finally, patch 9 documents how to build and install images for these
boards.

[Buildroot] [PATCH 1/9] arch/config: Make RISC-V MMU optional

[Damien Le Moal]

Linux supports No-MMU RISC-V since kernel version 5.8. Make MMU optional
to enable building for RISC-V boards that do not have one.

Using *-uclinux-* seems like an only partially followed convention.
And at least for RISC-V gcc doesn't know about uclinux tuples, so
switch back to the normal Linux one for now.

[Buildroot] [PATCH 4/9] board: Add Sipeed MAIX-bit support

[Damien Le Moal]

Add two configuration files to support the RISC-V Canaan K210 SoC based
Sipeed MAIX-bit board.

The first configuration file, sipeed_maix_bit_defconfig, enables
building a bootable kernel 5.13 image with the root file system
initramfs linked with the kernel. This configuration uses the busybox
busybox-tiny-initramfs.config configuration to reduce the size of the
busybox executable (to save memory when executing shell commands).

The second configuration file (sipeed_maix_bit_sdcard_defconfig) builds
a bootable kernel 5.13 image that uses the board SD card for the root
file system. This configuration uses the default busybox minimal
configuration.

Both configurations share the same device tree which is provided by and
built-in the kernel. This configuration is set with the kernel
configuration snippet provided by
board/sipeed/maix-bit/linux-dtb.config.

Both configurations also share the same init script provided using the
rootfs_overlay root file system overlay. This init script replaces the
default init process which causes failures due to excessive memory
usage.

busybox-tiny-initramfs.config and the init script overlay will be
reused for all Canaan K210 SoC based boards. These 2 files are thus
placed in the directory board/canaan/k210-common while the Sipeed
MAIX-bit board specific kernel config snippet is added under the
directory board/sipeed/maxi-bit.

Add two configuration files to support the RISC-V Canaan K210 SoC based
Sipeed MAIX-Go board. These configurations are similar to the Sipeed
MAIX-bit board configurations, differing only by the built-in device
tree used.

[Buildroot] [PATCH 9/9] board: Document Canaan K210 based boards support

[Damien Le Moal]

Add a generic board/canaan/k210-common/README.md file documenting how to
generate and install buildroot images for the Canaan K210 SoC based
boards. A simple README.md file pointing to this generic documentation
is also added under each K210 SoC board directory.

+# Canaan Kendryte K210 SoC Based Board Support
+
+Buildroot provides support for Canaan RISC-V Kendryte K210 SoC based boards.
+Configurations for different K210 Soc board variants are available. The boards
+supported are as follows.
+
+* From Sipeed: MAIX Bit, MAIX Dock (Dan Dock), MAIX Go and MAIXDUINO boards.
+
+* From Canaan: KD233 development board.
+
+For each board, two configurations are provided:
+
+* Configuration to build a bootable kernel image with built-in initramfs root
+file system (SD card is not used)
+
+* Configuration to build a bootable kernel image with the root file system
+on the board SD card.
+
+In all cases, the build process generates a bootable kernel image that can be
+directly flashed to the board boot flash. A boot loader (e.g. U-Boot) and
+OpenSBI are not necessary.
+
+## Bootable Kernel Image With A Built-In Initramfs Root File System
+
+The following table lists the default configuration provided for each board
+supported.
+
+| Board vendor and model | configuration name          |
+| ---------------------- | --------------------------- |
+| Canaan KD233           | canaan_kd233_defconfig      |
+| Sipeed MAIX bit        | sipeed_maix_bit_defconfig   |
+| Sipeed MAIX Go         | sipeed_maix_go_defconfig    |
+| Sipeed MAIX dock       | sipeed_maix_dock_defconfig  |
+| Sipeed MAIXDUINO       | sipeed_maixduino_defconfig  |
+
+The build procedure is similar for all boards. The steps to create the kernel
+bootable image are as follows:
+
+```
+$ make <config name>
+$ make
+```
+
+The build process will generate the bootable binary image file
+*output/images/loader.bin*. This image file must be written to the board boot
+flash using the
+[Sipeed kflash python utility](https://github.com/sipeed/kflash.py).
+
+```
+$ sudo python3 kflash.py -p /dev/ttyUSB0 -b 1500000 -t output/images/loader.bin
+```
+
+The above command will open a terminal console and reboot the board once the
+image is written. The output will be similar to the following (example obtained
+with the Sipeed MAIX Bit board).
+
+```

+## Bootable Kernel Image With the Root File System On SD Card
+
+The following table lists the default configurations provided for the supported
+boards.
+
+| Board vendor and model | configuration name                 |
+| ---------------------- | ---------------------------------- |
+| Canaan KD233           | canaan_kd233_sdcard_defconfig      |
+| Sipeed MAIX bit        | sipeed_maix_bit_sdcard_defconfig   |
+| Sipeed MAIX Go         | sipeed_maix_go_sdcard_defconfig    |
+| Sipeed MAIX dock       | sipeed_maix_dock_sdcard_defconfig  |
+| Sipeed MAIXDUINO       | sipeed_maixduino_sdcard_defconfig  |
+
+The build procedure is similar to the built-in initramfs case.
+
+```
+$ make <config name>
+$ make
+```
+
+The build process will generate two files under the *output/images* directory.
+
+* *loader.bin*: This bootable kernel image file.
+
+* *rootfs.ext2*: ext2 (rev1) SD card image.
+
+Before flashing the kernel bootable image, the SD card must be prepared.
+
+```
+$ sudo dd if=output/images/rootfs.ext2 of=/dev/sdX1 bs=1M
+$ sync
+$ eject /dev/sdX
+```
+
+Where */dev/sdX* is the device file name of the SD card. The SD card must have
+at least one partition of o at least 60 MB. Once completed, the SD card can be
+inserted into the board and the kernel bootable image file written to the board
+boot flas, using
+[Sipeed kflash python utility](https://github.com/sipeed/kflash.py).
+
+```
+$ sudo python3 kflash.py -p /dev/ttyUSB0 -b 1500000 -t output/image/loader.bin
+```
+
+The above command will open a terminal console and reboot the board once the
+image is written. The output will be similar to the following (example obtained
+with the Sipeed MAIX Bit board).
+
+```

Maybe simplify the conditions part like this:

ifeq ($(BR2_BINFMT_FLAT):$(BR2_riscv),y:)
TARGET_OS = uclinux
else
TARGET_OS = linux
endif

> The first configuration file, sipeed_maix_bit_defconfig, enables
> building a bootable kernel 5.13 image with the root file system
> initramfs linked with the kernel. This configuration uses the busybox
> busybox-tiny-initramfs.config configuration to reduce the size of the
> busybox executable (to save memory when executing shell commands).
>
> The second configuration file (sipeed_maix_bit_sdcard_defconfig) builds
> a bootable kernel 5.13 image that uses the board SD card for the root
> file system. This configuration uses the default busybox minimal
> configuration.
>
> Both configurations share the same device tree which is provided by and
> built-in the kernel. This configuration is set with the kernel
> configuration snippet provided by
> board/sipeed/maix-bit/linux-dtb.config.
>
> Both configurations also share the same init script provided using the
> rootfs_overlay root file system overlay. This init script replaces the
> default init process which causes failures due to excessive memory
> usage.
>
> busybox-tiny-initramfs.config and the init script overlay will be
> reused for all Canaan K210 SoC based boards. These 2 files are thus
> placed in the directory board/canaan/k210-common while the Sipeed
> MAIX-bit board specific kernel config snippet is added under the
> directory board/sipeed/maxi-bit.
