为了能在 DR1V90 上全面测试主线 Linux Kernel 以及方便开发，本人移植了一版（目前）还未 Upstream 的 mainline OpenSBI 以及 U-Boot（基于 MLKPAI FS01 开发板）。该 U-Boot 支持 USB host 以及 RTL8152 USB 网卡，使得可以通过网络启动 Linux。
准备
创建一个项目目录：
$ mkdir sdkproj && cd sdkproj
$ export ROOT=
准备用来编译 FSBL 的工具链：
$ wget https://download.nucleisys.com/upload/files/toolchain/gcc/nuclei_riscv_newlibc_prebuilt_linux64_2020.08.tar.bz2
$ tar -xf nuclei_riscv_newlibc_prebuilt_linux64_2020.08.tar.bz2
FSBL
编译 FSBL（该 sdk 整理自米联客发布的网盘压缩包资料中）：
$ git clone -b mlkpai-fs01 https://github.com/pigmoral/dr1v90_sdk.git
$ cd dr1v90_sdk/FSBL
$ make COMPILE_PREFIX=$ROOT/gcc/bin/riscv-nuclei-elf-
这会生成 build/FSBL.elf.
U-Boot
编译 U-Boot：
$ cd $ROOT
$ git clone -b dr1v90/init https://github.com/pigmoral/u-boot.git
$ cd u-boot
$ make CROSS_COMPILE=riscv64-linux-gnu- dr1v90_mlkpai_fs01_defconfig
$ make CROSS_COMPILE=riscv64-linux-gnu-
这会生成 u-boot.bin 以及 dts/upstream/src/riscv/anlogic/dr1v90-mlkpai-fs01.dtb。
OpenSBI
编译 OpenSBI：
$ cd $ROOT
$ git clone -b dr1v90/init https://github.com/pigmoral/opensbi.git
$ make CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic FW_FDT_PATH=$ROOT/u-boot/dts/upstream/src/riscv/anlogic/dr1v90-mlkpai-fs01.dtb
这会生成 build/platform/generic/firmware/fw_jump.bin.
打包
首先，获取 albg 程序（这似乎是 Xilinx bootgen 项目的 Anlogic fork）：
$ cd $ROOT
$ mkdir packproj && cd packproj
$ wget -O albg https://gitee.com/anlogic/sdk/raw/anlogic-linuxsdk/tools/bootgen/linux64/bin/albg1
$ chmod +x albg
准备一份打包配置文件：
cat << 'EOF' > bootgen.bif
/* arch=dr1v90; split=false; format=BIN */
the_ROM_image:
{
[
bootloader
,destination_cpu=rpu
] FSBL.elf
[
destination_cpu=rpu
,load=0x0
,exec=0x0
,org_endian
,partition_owner=fsbl
] fw_jump.bin
[
destination_cpu=rpu
,load=0x200000
,exec=0xFFFFFFFF
,org_endian
,partition_owner=fsbl
] u-boot.bin
}
EOF
拷贝固件到当前目录：
$ cp $ROOT/dr1v90_sdk/FSBL/build/FSBL.elf .
$ cp $ROOT/u-boot/u-boot.bin .
$ cp $ROOT/opensbi/build/platform/generic/firmware/fw_jump.bin .
此时我们目录下应有这些文件：
.
├── albg
├── bootgen.bif
├── FSBL.elf
├── fw_jump.bin
└── u-boot.bin
执行打包命令：
$ ./albg -image ./bootgen.bif -arch dr1v90 -o ./BOOT.bin
这会生成 BOOT.bin，我们只需要将其放入 SD 卡的第一个 fat 分区中启动即可。
