13.2.3.1. Boot ROM Clocks

The boot ROM is driven by the l3_main_clk interconnect clock.

The boot ROM needs to set up the Main PLL and make sure it sources all of the system's clocks. The sequence applied for both Warm and Cold resets is similar. The PLL's are not set up on an FPGA boot, a successful RAM boot, or if the user selects a bypass mode.
