RISC-V 开发板系统镜像安装工具，增加4款RISC-V开发板

[xijing21]

扩展4款支持的开发板（全dd模式）：矽速 Lichee RV 、 全志哪吒 D1、VisionFive 1 & 2；

D1 / Lichee RV & Nezha:

• 镜像（openEuler 23.03，两款开发板共用）: https://mirror.iscas.ac.cn/openeuler-sig-riscv/openEuler-RISC-V/preview/openEuler-23.03-V1-riscv64/D1/
• 文档：https://gitee.com/openeuler/RISC-V/blob/master/release/openEuler-23.03/Installation_Book/D1_and_Licheerv/README.md

VisionFive:

• 镜像（openEuler 23.09 Preview）: https://mirror.iscas.ac.cn/openeuler-sig-riscv/openEuler-RISC-V/preview/openEuler-23.09-V1-riscv64/Visionfive/
• 文档：https://gitee.com/openeuler/RISC-V/blob/master/release/openEuler-23.03/Installation_Book/Visionfive/README.md

VisionFive 2:

• 镜像（openEuler 23.09 Preview）：https://mirror.iscas.ac.cn/openeuler-sig-riscv/openEuler-RISC-V/preview/openEuler-23.09-V1-riscv64/Visionfive2/

Proposed device model slugs:

• sipeed-licheerv: Sipeed didn't have an official abbreviation for it according to the wiki page (see the page URL; in contrast, LicheePi 4A is officially abbreviated as lpi4a).
• awol-d1dev: official product page is https://d1.docs.aw-ol.com/d1_dev/ (certificate is expired though), hence awol and d1 ("Nezha" seems only a brand name that's not part of the codename)
• starfive-visionfive: officially called so: https://github.com/starfive-tech/VisionFive
• starfive-visionfive2: officially called so: https://github.com/starfive-tech/VisionFive2

Is that okay?

And -- is "Lichee RV" actually compatible enough with "Nezha D1" so that they'd be better represented as one model?

In openEuler RISC-V 23.03 they shares the same system image, but different DTBs. Although even with Nezha D1's DTB selected (by default), Lichee RV can still boot & operate without any issues. I think this is fine.

As in the bootloader / GRUB config of the image says:

menuentry 'openEuler riscv64 6.1.0 Nezha' {
    linux /vmlinuz-openEuler rw earlyprintk=sunxi-uart,0x02500000 console=ttyS0,115200 console=tty0 loglevel=8  root=/dev/mmcblk0p4 selinux=0 rhgb LANG=en_US.UTF-8
    devicetree /dtbs/allwinner/sun20i-d1-nezha.dtb
}

menuentry 'openEuler riscv64 6.1.0 Lichee RV Dock' {
    linux /vmlinuz-openEuler rw earlyprintk=sunxi-uart,0x02500000 console=ttyS0,115200 console=tty0 loglevel=8  root=/dev/mmcblk0p4 selinux=0 rhgb LANG=en_US.UTF-8
    devicetree /dtbs/allwinner/sun20i-d1-lichee-rv-dock.dtb
}

With that said, there are some differences between two boards. I'll do some testing later.

Booting as default (use AllWinner Nezha's dtb) on Lichee RV Dock:

These two boards share the same SoC, only some peripherals are different. For example there's no ethernet PHY present on Lichee RV Dock. Other features will work just fine (e.g. WiFi, BT, USB, HDMI video out). You can say it's "compatible enough".

While it does work, there will be some differences. Users are recommended to change their GRUB defaults settings.

they share the same system image, but different DTBs

So from a user's perspective, they are different models if the user wishes to make use of all features provided by the hardware, although a lot of code is shared.
