On that note, I think the inaccurate docs about polarfire should be removed. There's a wiki page here with dead links, or links to things that do not work anymore: https://wiki.qemu.org/Documentation/Platforms/RISCV#Microchip_PolarFire_SoC_Icicle_Kit I think the whole section should be removed, find it kinda odd that there's a polarfire section but not for any other board. Either way, it's talking about something that just does not work, the current HSS and Yocto don't boot. There's also a docs page here: https://www.qemu.org/docs/master/system/riscv/microchip-icicle-kit.html that has a copy of the table your patch 4 modifies, that probably should be updated to match your changes. In a similar vein to the wiki, it talks about the HSS and booting a yocto wic image. I think those should be deleted since they don't work. Alistar/Other RISC-V folks, what do you think? Bin wrote the port but seems to be AFK and I don't have the capacity to fix any of that stuff on top of what I already do in my spare time - do you agree that deleting the now inaccurate docs makes sense? > In order to allow tests runs for real-time kernels such as RTEMS and > Zephyr, improve the boot customization.

The file does exist, so probably some sort of path-to-it issues?
