[PATCH 0/2] fix issues in bootmenu after adding efi entries
This series fixes the issue in bootmenu after adding efi entries.
Masahisa Kojima (2): bootmenu: use utf-8 for menu title bootmenu: U-Boot console is enabled as default
boot/Kconfig | 9 +++++++++ cmd/Kconfig | 10 ---------- cmd/bootmenu.c | 40 +++++++++++++++++++++++----------------- 3 files changed, 32 insertions(+), 27 deletions(-)
The commit a3d0aa87acbe ("bootmenu: update bootmenu_entry structure") changes the bootmenu title type from char to u16(UTF16 string) to support EFI based system. If EFI_LOADER is not enabled, printf("%ls") is not supported, so bootmenu does not appear correctly.
This commit changes the type of menu title from u16(UTF16) to utf-8 string and EFI strings is conveted into utf-8.

The commit 2158b0da220c ("bootmenu: add Kconfig option not to enter U-Boot console") disables to enter U-Boot console from bootmenu as default, this change affects the existing bootmenu users.
This commit reverts the default behavior, the bootmenu can enter U-Boot console same as before. CMD_BOOTMENU_ENTER_UBOOT_CONSOLE is renamed BOOTMENU_DISABLE_UBOOT_CONSOLE and depends on AUTOBOOT_MENU_SHOW.

Remove this line. It is default option anyway.
