Initialization Code
Introduction
Initialization code is part of a boot stream and can be seen as a special boot
block. While normally all boot blocks of an application are booted in first
and control is passed to the application afterward, the initialization code
executes at boot time. It is common that an initialization code is booted
and executed before any other boot block. This initialization code can customize
the target system for optimized boot processing.
Global Header
Some boot kernels expect a boot stream to be headed by a special information
tag. The tag is referred to as a global header.
Boot Strapping
If the boot process consists of multiple steps, such as pre-loading the boot
kernel or managing second-stage loaders, this is called boot strapping.
Slave Boot
The term slave boot spawns all boot modes where the target processor
functions as a slave. This is typically the case when a host device loads data
into the target processor’s memories. The target processor can wait passively
in idle mode or support the host-controlled data transfers actively.
Note that the term host boot usually refers only to boot modes that are
based on so-called host port interfaces.
Master Boot
The term master boot spawns all boot modes where the target processor
functions as master. This is typically the case when the target processor
reads the boot data from parallel or serial memories.
