Hi Simon,
I see you have put support for the MinnowBoard Max in the u-boot mainline. Thanks this is a very useful addition. I have been able to follow your readme and build a working bare metal uboot. Using the built uboot I can load and bring up a Linux Kernel.
What I noticed from the running kernel is that only one of the two cores on the E3825 is running. In the power PC uboots I usually see a section for the multiple cores in the .dts file. My questions is how do I get both CPUs running on this board. Is it a uboot .dts file setup that will enable this, or is something in the kernel start up that does this.
As a test I boot the same kernel using the EFI BIOS on the minnow board and both CPUs are running.
Any suggestions or comments you have would be welcomed.
My guess is that the LAPIC CPU start-up is missing. It isn't 100% clear what the FSP does and does not do, but perhaps it does not do that.
I did make something of a start on this with ivybridge but it isn't complete, and it seems to be needed here.
Regards, Simon
