AM33xx sysboot settings

AM33xx document is not very clear on the sysboot settings. Recently when working on it I had some trouble finding out where in the document the SYSBOOT[15:0] pins correspond to the LCD_DATA[51:0] inputs. It is in page 5033 of spruh73p documentation in chapter 26.1.6 Booting, Device list and sub chapter SYSBOOT CONFIGURATION.

To quote:

"SYSBOOT[15:0] terminals are respectively LCD_DATA[15:0] inputs, latched on the rising edge of PWRONRSTn."
