Hi, I am currently examining the posibility of multiple operating systems on embedded devices. After some research I found out that amp is possible on a freescale p2020 using u-boot. There is a simple description in README.p2020rdb which includes the u-boot commands fdt and cpu. I know that fdt is used to manipulate device trees and cpu is used for cpu activate, deactivate and release of the power mpc85xx and mpc86xx cpus. I had a look at arch/powerpc/cpu/mpc85xx/mp.c and arch/powerpc/cpu/mpc85xx/fdt.c.

My question is: Is there a similar implementation for the OMAP4430 mp cpus?

Is it generally possible to boot two independent operating systems on an OMAP4430 platform using u-boot?

Thanks Clemens
