I guess you are asking about the “Execute-In-Place (XIP)” booting mode – it is supported (see the “19.5.1.2 QuadSPI Serial Flash BOOT Operation” section of the “Vybrid Reference Manual, Rev. 5, 07/2013”):
"Both booting an XIP and non-XIP image is supported from serial flash. For XIP boot, the image has to be built for QuadSPI address space, and for non-XIP the image can be built to execute from DDR or SRAM."
Please, also take a look at the “19.5.1.6 QuadSPI boot flow chart”.
