Alistair Francis 40e46e516d riscv: Ensure the kernel start address is correctly cast ... Cast the kernel start address to the target bit length. This ensures that we calculate the initrd offset to a valid address for the architecture. Steps to reproduce the original problem (reported by Alex): Build U-Boot for the virt machine for riscv32. Then run it with $ qemu-system-riscv32 -M virt -kernel u-boot -nographic -initrd <a file> You can find the initrd address with U-Boot# fdt addr $fdtcontroladdr U-Boot# fdt ls /chosen Then take a peek at that address: U-Boot# md.b <addr> and you will see that there is nothing there without this patch. The reason is that the binary was loaded to a negative address.
