Subject: [RESEND v9 5/9] eficonfig: add "Change Boot Order" menu entry
Date: Fri, 15 Jul 2022 23:47:45 +0900 [thread overview]
Message-ID: <20220715144749.30564-6-masahisa.kojima@linaro.org> (raw)
In-Reply-To: <20220715144749.30564-1-masahisa.kojima@linaro.org>
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.
