This patch series adds the menu-driven boot device selection,
by extending the existing "bootmenu" to include UEFI and distro_boot
related entries, and supports menu-driven UEFI boot variable
maintenance.
This patch series also includes the removable media support
that UEFI specification requires to support.
The menu example is as follows.
*** U-Boot Boot Menu ***
bootmenu_00 : Boot 1. kernel
bootmenu_01 : Boot 2. kernel
bootmenu_02 : Reset board
UEFI BOOT0000 : debian
UEFI BOOT0001 : ubuntu
UEFI BOOT0002 : mmc0:1
UEFI BOOT0003 : mmc0:2
UEFI BOOT0004 : nvme0:1
UEFI BOOT0005 : nvme0:2
UEFI BOOT0006 : usb0:2
UEFI BOOT0007 : usb1:1
UEFI BOOT0008 : usb1:2
distro_boot : usb0
distro_boot : scsi0
distro_boot : virtio0
distro_boot : dhcp

[How to run on QEMU(arm64)]
1) clone source code
$ git clone https://git.linaro.org/people/masahisa.kojima/u-boot.git \
-b kojima/bootmenu_v4_upstream_0324 --depth 1
2) prepare 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
