Hi,
I have a query regarding U-Boot. Is it possible to boot two separate OS on
a Dual/multi core processor using U-Boot. I want to implement AMP on a dual
core processor and want to run two separate OS on a dual core arm cortex a9
processor. Did anybody tried the same thing earlier using the U-Boot.
Any kind of help will be highly appreciated..
Thanks and Regards,
Sandeep

We've done this on powerpc, using bootm subcommands to prepare the
device tree, and then the "cpu" command in common/cmd_mp.c to boot
something on the second core.

There are a few powerpc examples in doc/ directory too, eg
doc/README.p2020rdb. Grepping for 'AMP' should find some more.
Best,
