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)] 1) clone source code $ 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
[Changes in v3]
- Major difference from previous version is that this version extends the existing bootmenu capability instead of updating efi bootmgr. - include distro_boot entries - "bootefi bootindex" command is newly added
