NXP iMX6UL processor implements a very flexible boot process. This versatility comes at the price of a non trivial bootstrap configuration scheme. Typical system-on-module (SOM for short) adopter does not need to deal with such a complexity. In other words, he/she expects to manage few boot configuration issues because it is assumed that most of them are "hidden" within the SOM itself. Nevertheless, there are specific applications where the system integrator needs full control of all the bootstrap configuration options, even if the design is built upon a SOM.
