Lukas Auer 66ffe5783b riscv: qemu: detect and boot the kernel passed by QEMU
QEMU embeds the location of the kernel image in the device tree. Store
this address in the environment as variable kernel_start. It is used in
the board-local distro boot command QEMU to boot the kernel with the
U-Boot device tree. The QEMU boot command is added as the first boot
target device.
