U-Boot: This is also called the Universal Bootloader and is available mostly for PowerPC and ARM architectures for embedded Linux systems

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...
