 Previously this was submitted in 2019
 https://patchwork.ozlabs.org/project/uboot/patch/20190821190720.4286-1-david.abdurachmanov@sifive.com/

 Since then the sifive fu540 portion of this change was merged, but
 not the qemu one.

 Submitting the qemu portion again. Without this change, qemu smode
 cannot boot Ubuntu's riscv64 cloud images with extlinux.conf.
