The PMC includes three types of flash memory controllers, any of which can be used as a boot device or by the application. The following table shows the difference between the flash memory controllers in Zynq UltraScale+ MPSoCs and Versal adaptive SoCs.

Table 1. Flash Memory Controllers Comparison
Peripheral	Zynq UltraScale+ MPSoC	Versal Adaptive SoC
Octal SPI (OSPI)	N/A	1 controller
Quad SPI (QSPI)	1 controller	1 controller that does not support linear address mode
SD/eMMC	2 controllers	2 controllers with the same functionality and updated DLL

Note: Versal adaptive SoCs can also support secondary boot modes (e.g., Ethernet, USB, etc.). For more information, see the Versal Adaptive SoC System Software Developers Guide (UG1304).
