Texas Instruments Sitara AM437x series: Some sequencing patterns are listed in the datasheet Power-Up Sequencing chapter. What are the differences?
The power-up sequence differs depending on whether the function is enabled or disabled. For example, Figure 5-7 shows the sequence for disabling the RTC function and using both 1.8V/3.3V for the IO power supply. I think you can judge from the title of the figure, so please take a look.
See datasheet for details.
