Set fdt_addr variable, which is needed for extlinux to find FDT. Otherwise booting kernel using extlinux results in missing FDT.
Also run fdt addr with FDT address so that fdt commands would work out of the box in U-Boot prompt.
While often useful to have, the fdt command is not used during a normal boot. I think we should avoid calling commands, which are not normally needed. Can you remove this from your patch?
Thanks, Lukas
This is successfully used by Fedora/RISCV with 5.1-rc3+ kernel using OpenSBI -> U-Boot (S-mode) [extlinux] -> Kernel setup.
