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
