the OpenSBI firmware, becoming the boot stage following the OpenSBI firmware

The current stable upstream code of U-Boot does not yet include all patches

necessary to fully support OpenSBI. To use U-Boot as an OpenSBI payload, the

following out-of-tree patch series must be applied to the upstream U-Boot source

This patch series enables a single CPU to execute U-Boot. As a result, the next
|

stage boot code such as a Linux kernel can also only execute on a single CPU.

U-Boot SMP support for RISC-V can be enabled with the following additional

Building and Generating U-Boot images
|
||||
=====================================
|
||||
Please refer to the U-Boot build documentation for detailed instructions on
|
||||
how to build U-Boot images.
|
||||
how to build U-Boot image and boot high level operating systems from U-Boot
|
||||
prompt.
|
||||
|
||||
Once U-Boot images are built, the Linux kernel image needs to be converted
|
||||
into a format that U-Boot understands:
|
||||
|
||||
```
|
||||
<uboot-dir>/tools/mkimage -A riscv -O linux -T kernel -C none -a 0x80200000 -e 0x80200000 -n Linux -d \
|
||||
<linux_build_directory>arch/riscv/boot/Image \
|
||||
<linux_build_directory>/arch/riscv/boot/uImage
|
||||
```
|
||||
|
||||
Copy the uImage to your tftpboot server path if network boot is required.
