Booting the processor on a Xilinx Zynq 7000 before the logic
Yes, the processor subsystem (PS) boots before the programmable logic (PL) is configured. Chapter 6 of the Zynq-7000 SoC Technical Reference Manaul covers this topic in some detail.

The only way to bypass this sequence is to configure the PL directly through its hardware JTAG interface.
