This commit adds the menu entry to update UEFI BootOrder variable. User moves the entry with UP/DOWN key, changes the order with PLUS/MINUS key, then finalizes the order by ENTER key. The U-Boot menu framework is well designed for static menu, this commit implements the own menu display and key handling for dynamically change the order of menu entry. Signed-off-by: Masahisa Kojima <masahisa.kojima@linaro.org> --- Changes in v7: - use UP/DOWN and PLUS/MINUS key to change to order no update in v6: cmd/efimenu.c | 207 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 207 insertions(+)
