[U-Boot] [PATCH 0/3] uefi: support USB boot in distro boot

[U-Boot] [PATCH 0/3] uefi: support USB boot in distro boot

[AKASHI Takahiro]

I think that it will be nice if we can install a distro linux from, say,
USB memory with ISO image, to a hard disk off the shelf.
Even with the current u-boot, we can do this by having two *scsi* disks,
but using an USB device looks more realistic, doesn't it?

This patch set give us a base for this; I was able to successfully start
a familiar "install" screen on qemu, using an ubuntu server ISO image for
arm64. CUI of course.

Thanks,
-Takahiro Akashi

[U-Boot] [PATCH 1/3] efi_loader: support USB boot in distro boot script

[AKASHI Takahiro]

With this patch, a removable USB mass storage device attached to the system
will also be scanned to find and boot an EFI binary (that is BOOTEFI_NAME,
see config_distro_bootcmd.h).

I can't see how this patch is needed - "usb dev" is a valid command
(via do_usb() -> blk_common_cmd()) as long as CONFIG_USB_STORAGE is set.

Right.
I didn't notice this sub-command, dev, because I first consulted
"help usb" with default qemu_arm64_defconfig which doesn't have
CONFIG_USB_STORAGE. Since then I've believed it was not available.

Yet my patch #2&#3 should work.

Yes, distro boot already supports USB booting just fine. All you need to
do is what you did in patch 3 to enable it on a particular target board.
