This example shows how to create a boot image with pmu_fw.elf loaded by BootROM.

the_ROM_image: 
{ 
	[pmufw_image] pmu_fw.elf 
	[bootloader, destination_cpu=a53-0] fsbl_a53.elf 
	[destination_cpu=r5-0] app_r5.elf
}

This example shows how to create a boot image with pmu_fw.elf loaded by BootROM. If PMU firmware is specified with attribute [pmufw_image], then PMU firmware is not treated as a separate partition. It is appended to the FSBL, FSBL and PMU firmware together becomes one single large partition. Hence, you cannot not see the PMU firmware in the Bootgen log as well.
