+Subject: [PATCH 1/3] menu: fix the logic checking whether ESC key is pressed
+
+It's observed that the bootmenu on a serial console sometimes
+incorrectly quitted with superfluous characters filled to command
+line input:
+
+> *** U-Boot Boot Menu ***
+>
+> 1. Startup system (Default)
+> 2. Upgrade firmware
+> 3. Upgrade ATF BL2
+> 4. Upgrade ATF FIP
+> 5. Load image
+> 0. U-Boot console
+>
+>
+> Press UP/DOWN to move, ENTER to select, ESC to quit
+>MT7988> [B
+
+Analysis shows it was caused by the wrong logic of bootmenu_loop:
+
+At first the bootmenu_loop received the first ESC char correctly.
+
+However, during the second call to bootmenu_loop, there's no data
+in the UART Rx FIFO. Due to the low baudrate, the second char of
+the down array key sequence hasn't be fully received.
+
+But bootmenu_loop just did a mdelay(10), and then treated it as a
+single ESC key press event. It didn't even try tstc() again after
+the 10ms timeout.
+
+This patch fixes this issue by letting bootmenu_loop check tstc()
+twice.

+Subject: [PATCH 2/3] menu: add support to check if menu needs to be reprinted
+
+This patch adds a new callback named need_reprint for menu.
+The need_reprint will be called before printing the menu. If the
+callback exists and returns FALSE, menu printing will be canceled.
+
+This is very useful if the menu was not changed. It can save time
+for serial-based menu to handle more input data.
