Hi,

I have a special question about reserved memory regions one some architectures. For the first time only for ARM and ARM64.

Is there a equivalent or similar mechanism in U-Boot to tell the Kernel, which memory regions are free available for the Kernel? On x86 with GRUB as boot loader, I can use the Multiboot specification. Does the device trees handle this? Unfortunately I haven't found any hint in the DTS at this time.

Started to write my own Kernel for the purpose of learning and want to port it to ARM. I also want to use U-Boot (for basic initialization) as loader for the Kernel, hence the question.

Thanks in advance!

Can U-Boot also boot ELF files from a FIT image? Tried it with "standalone" and "kernel", but didn't work for me.
