+Switch Setting for Boot Mode
+----------------------------
+
+Boot Mode pins provide means to select the boot mode and options before the
+device is powered up. After every POR, they are the main source to populate
+the Boot Parameter Tables.
+
+The following table shows some common boot modes used on AM62 platform. More
+details can be found in the Technical Reference Manual:
+https://www.ti.com/lit/pdf/spruiv7 under the `Boot Mode Pins` section.
