This patch series adds the menu-driven boot device selection,
by extending the existing "bootmenu" to include UEFI and distro_boot
related entries.
The menu example shown with this patch series is as follows.
*** U-Boot Boot Menu ***
Boot 1. kernel (bootmenu_0)
Boot 2. kernel (bootmenu_1)
Reset board (bootmenu_2)
debian (BOOT0000)
ubuntu (BOOT0001)
UEFI Boot Manager
usb0
scsi0
virtio0
dhcp
UEFI Boot Manager Maintenance
U-Boot console
Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit
This example shows three "bootmenu_0..2" entries, UEFI "Boot0000" and "Boot0001"
entries, distro_boot "boot_targets" entries(usb0, scici0, virtio0 and dhcp)
and some pre-defined entries(UEFI Boot Manager, UEFI Boot Manager Maintenance
and U-Boot console).
Note that this patch series aims to propose the above menu structure,
the code quality is very low and requires much cleanup/refactoring.
[How to run on QEMU(arm64)]

$ git clone https://git.linaro.org/people/masahisa.kojima/u-boot.git \
-b kojima/efibootmenu_v3_upstream --depth 2
2) update U-Boot .config
$ make qemu_arm64_menuconfig
then, enable CONFIG_CMD_BOOTMENU and CONFIG_AUTOBOOT_MENU_SHOW
3) run on QEMU(arm64) example
$ qemu-system-aarch64 -machine virt,gic-version=3 -cpu cortex-a57 -m 4G
-nographic \
-no-acpi -bios ./u-boot.bin -hda xxx.img
