From ba51269f75e99024b8e3c904b0964f3dcb3cd629 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 23 Jun 2020 05:23:15 -0700 Subject: doc: qemu-riscv: Update QEMU run command Explicitly pass the "-bios" option to QEMU to run U-Boot, instead of the "-kernel" option, as we know that "-bios" behavior will be changed since QEMU 5.1.0. This also updates validated QEMU version to 5.0.0.
