[PATCH v2 0/3] riscv: sophgo: milkv_duo: add support for Milk-V Duo board
The Milk-V Duo board is built upon Sophgo's CV1800B SoC, featuring two XuanTie C906 CPUs running at 1.0GHz and 700MHz, respectively.
This series introduces fundamental support for the Milk-V Duo board, encompassing UART, CPU, and PLIC support. This ensures that U-Boot can operate in serial console mode.
Changes in v2: - Fold the defconfig patch to first patch - Remove unnecessary environment settings of consoledev and baudrate in config

Add support for Sophgo's Milk-V Duo board, only minimal device tree and serial console are enabled, and it can boot via vendor first stage bootloader.

The sequence of patches seems to be wrong.
We expect that after each single patch building succeeds. But the device-tree is neither in this patch nor in a preceding patch. Please, swap patch 1 and 2.

Is there a limitation on the size of the binary or why are you excluding this option?
With the loady command you should be able to load an EFI binary via the UART and then launch it. U-Boot comes with some EFI test applications that you could run like smbiosdump.efi.

In my memory, enabling the CONFIG_EFI_LOADER option resulted in some errors on this board, but I forgot what those errors were. I will verify it, and if there are no issues, I will enable this option.

I'd like to clarify your request for describing the procedure to run u-boot-dtb.bin on top of FSBL. Are you looking for a detailed, step-by-step guide to replicate the process and successfully run u-boot-dtb.bin, or would you prefer a more concise overview?
