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.
