cbea241e93 efidebug: add multiple device path instances on Boot####
The UEFI spec allows a packed array of UEFI device paths in the
FilePathList[] of an EFI_LOAD_OPTION. The first file path must
describe the loaded image but the rest are OS specific.

Previous patches parse the device path and try to use the second
member of the array as an initrd. So let's modify efidebug slightly
and install the second file described in the command line as the
initrd device path.

ed1475e2f4 riscv: qemu: Remove the simple-bus driver for the SoC node
Prior to QEMU v3.1.0, QEMU generated the 'virt' SoC node with a
"riscv-virtio-soc" compatible string, and a "simple-bus" driver
was created to accommodate that special case in U-Boot.

Starting from QEMU v3.1.0, the SoC node was set as a "simple-bus",
hence the special simple-bus driver is no longer needed.

Update the doc to mention the latest tested QEMU version 4.2.0.

bfaa54f912 doc: board: qemu-mips.rst: fix code examples
Code sections should be syntax highlighted as bash.
Comment lines in code should start with a hash sign ('#') but code lines
should not.
Most commands can be executed as normal users. Prepend those commands
requiring elevated authorization with 'sudo'.
dd does not have a parameter cout.
sfdisk does not have a -C parameter on Debian Buster.
Provide the necessary input to sfdisk.
Creating a partition of length zero makes no sense.

00f237e226 qemu-x86: Use config_distro_bootcmd
Converts qemu x86 machines to boot using distro_config. The intent is to
allow u-boot in qemu to be maximally compatible with many boot methods
without having to change the config. Previously, u-boot would only boot
in a very limited set of circumstances where there was a /boot/vmlinuz
on scsi 0:3 with no ramdisk.
