Re: [PATCH v12 00/18] RISC-V SiFive FU540 support SPL

Hi Pragnesh,

This series add support for SPL to FU540. U-Boot SPL can boot from L2 LIM (0x0800_0000) and jump to OpenSBI(FW_DYNAMIC firmware) and U-Boot proper from MMC devices.

This series is also available here [1] for testing [1] https://github.com/pragnesh26992/u-boot/tree/spl

How to test this patch:

1. Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y

2. export OPENSBI=<path to opensbi/build/platform/generic/firmware/fw_dynamic.bin>

3. Change to u-boot-dir

4. make sifive_fu540_defconfig

5. make all

6. Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)

    # sudo sgdisk --clear \
    > --set-alignment=2 \
    > --new=1:34:2081 --change-name=1:loader1 --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \

    > /dev/sda
   
   

7. sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=34

8. sudo dd if=u-boot.itb of=/dev/sda seek=2082

Changes in v12:

• Rebase on mainline U-Boot Added necessary include files which are not part of common header now Remove unnecessary include files

  drivers/misc/sifive-otp.c +#include <linux/bitops.h> +#include <linux/delay.h>

  board/sifive/fu540/fu540.c -#include <common.h> +#include <log.h>

  board/sifive/fu540/spl.c +#include <init.h> +#include <log.h> +#include <linux/delay.h>

  drivers/ram/sifive/fu540_ddr.c +#include <linux/bitops.h>

  arch/riscv/cpu/fu540/cpu.c -#include <common.h> +#include <asm/cache.h>

  arch/riscv/cpu/fu540/spl.c -#include <common.h> +#include <log.h>

  board/sifive/fu540/spl.c -#include <common.h> +#include <init.h> +#include <log.h> +#include <linux/delay.h>

• Update commit description for Release ethernet clock reset

• Update OpenSBI building section in "doc/board/sifive/fu540.rst"

Thanks. During the testing I found there is one issue about ethernet.

The 1000Mbps does not work. Only 100Mbps works. Could you please have a look?
