Comparing various bootloaders
As we read earlier, a number of bootloaders are available for embedded systems. The ones that will be presented here are as follows:
U-Boot: This is also called the Universal Bootloader and is available mostly for PowerPC and ARM architectures for embedded Linux systems
Barebox: This was initially known as U-Boot v2 and was started in 2007 with the scope to solve the limitations of U-Boot; it changed its name over time because the design goals and community changed
RedBoot: This is a RedHat bootloader derived from eCos, an open-source real-time operating system that is portable and devised for embedded systems
rrload: This is a bootloader for ARM and is based on embedded Linux systems
PPCBOOT: This is a bootloader for PowerPC and is based on embedded Linux systems
CLR/OHH: This represents a flash bootloader for embedded Linux systems based on an ARM architecture
Alios: This is a bootloader that is written mostly in assembler, does ROM and RAM initializations...
