I am able to run seL4test on a RPi4 without any changes to the elfloader using the latest U-Boot, maybe older U-Boot versions did not support EFI images? |
Cherry-pick 'smp.c' and 'smp_head.S' from ARM Research IceCap repository for BCM2711 platform. Commit ID: b2b92939bf94443e7bf13a15801561ef7caf565d URL: https://gitlab.com/icecap-project/seL4_tools/-/commit/<SHA> UART support files are not selected from the commit, as kernel correctly generates header(s) for the 'bcm2835-aux-uart', which is the same as on RPi3, and the common 'bcm-uart.c' driver can be used for RPi4 too.

Hi Ivan, thanks for your comment. I also tested with the latest U-Boot, and it seems that you are correct and the image can be booted with 'bootefi'. I think I had something misconfigured before, and I couldn't boot the image. I removed the commit for changing the image type. |
