Syntax

[early_handoff] <partition>

Description

This flag ensures that the handoff to applications that are critical immediately after the partition is loaded; otherwise, all the partitions are loaded sequentially and handoff also happens in a sequential fashion.

Note: In the following scenario, the FSBL loads app1, then app2, and immediately hands off the control to app2 before app1.

Example

all:
{
	[bootloader, destination_cpu=a53_0]fsbl.el
	[destination_cpu=r5-0]app1.elf
	[destination_cpu=r5-1,early_handoff]app2.elf
}
