----------
'-cpu pentium' won't work for obvious reasons that the processor only
supports 32-bit.
-Note 64-bit support is very preliminary at this point. Lots of features
-are missing in the 64-bit world. One notable feature is the VGA console
-support which is currently missing, so that you must specify '-nographic'
-to get 64-bit U-Boot up and running.
+Booting distros
+---------------
+
+It is possible to install and boot a standard Linux distribution using
+qemu-x86_64 by setting up a root disk::
+
+ qemu-img create root.img 10G
+
+then using the installer to install. For example, with Ubuntu 2023.04::
+
+ qemu-system-x86_64 -m 8G -smp 4 -bios /tmp/b/qemu-x86_64/u-boot.rom \
+ -drive file=root.img,if=virtio,driver=raw \
+ -drive file=ubuntu-23.04-desktop-amd64.iso,if=virtio,driver=raw
+
+You can also add `-serial mon:stdio` if you want the serial console to show as
+well as the video.
+
+The output will be something like this::
+
+ U-Boot SPL 2023.07 (Jul 23 2023 - 08:00:12 -0600)
+ Trying to boot from SPI
+ Jumping to 64-bit U-Boot: Note many features are missing

+
+Standard boot looks through various available devices and finds the virtio
+disks, then boots from the first one. After a second or so the grub menu appears
+and you can work through the installer flow normally.
+
+Note that standard boot will not find 32-bit distros, since it looks for a
+different filename.
+
+Current limitations
+-------------------
+
+Only qemu-x86-64 can be used for booting distros, since qemu-x86 (the 32-bit
+version of U-Boot) seems to have an EFI bug leading to the boot handing after
+Linux is selected from grub, e.g. with `debian-12.1.0-i386-netinst.iso`::
+
+ ** Booting bootflow 'virtio-blk#1.bootdev.part_2' with efi
+ EFI using ACPI tables at f0180
+ efi_install_fdt() WARNING: Can't have ACPI table and device tree - ignoring DT.
+ efi_run_image() Booting /efi\boot\bootia32.efi
+ Failed to open efi\boot\root=/dev/sdb3 - Not Found
+ Failed to load image 큀緃: Not Found
+ start_image() returned Not Found, falling back to default loader
+ Welcome to GRUB!
+
+The bochs video driver also seems to cause problems before the OS is able to
+show a display.
+
+Finally, the use of `-M accel=kvm` is intended to use the native CPU's
+virtual-machine features to accelerate operation, but this causes U-Boot to hang
+when jumping 64-bit mode, at least on AMD machines. This may be a bug in U-Boot
+or something else.
The bootdev device is typically created automatically in the media uclass'
`post_bind()` method by calling `bootdev_setup_for_dev()` or
-`bootdev_setup_sibling_blk()`. The code typically something like this::
+`bootdev_setup_for_sibling_blk()`. The code typically something like this::
/* dev is the Ethernet device */
ret = bootdev_setup_for_dev(dev, "eth_bootdev");
or::
/* blk is the block device (child of MMC device)
- ret = bootdev_setup_sibling_blk(blk, "mmc_bootdev");
+ ret = bootdev_setup_for_sibling_blk(blk, "mmc_bootdev");
if (ret)
return log_msg_ret("bootdev", ret);
echo CONFIG_SYS_BOARD boot failed - please check your image
echo Load address is CONFIG_SYS_LOAD_ADDR
+Settings which are common to a group of boards can use #include to bring in
+a common file in the `include/env` directory, containing environment
+settings. For example::
+
+ #include <env/ti/mmc.env>
+
If CONFIG_ENV_SOURCE_FILE is empty and the default filename is not present, then
the old-style C environment is used instead. See below.
Board maintainers are encouraged to migrate to the text-based environment as it
is easier to maintain. The distro-board script still requires the old-style
-environment but work is underway to address this.
+environments, so use :doc:`../develop/bootstd` instead.
