About U-boot
The \"U-Boot\" Universal Bootloader project provides firmware with full source code under
GPL. Many CPU architectures are supported: PowerPC (MPC5xx, MPC8xx, MPC82xx,
MPC7xx, MPC74xx, 4xx), ARM (ARM7, ARM9, StrongARM, Xscale), MIPS (4Kc, 5Kc),
x86, etc.
4.1.2
U-boot for COMX-P2020
Since the U-boot has supported a range of CPU architectures including PowerPC
(MPC5xx, MPC8xx, MPC82xx, MPC7xx, MPC74xx, 4xx, QorIQ) while P2020 is a base-on-
supported-QorIQ processor, it is possible, as well as useful, to provide the U-boot firmware
as the COMX-P2020 bootloader.
COMX-P2020 only supports starting-up U-boot from SPI Flash and SD Card.
