Re: [U-Boot] MinnowBoard Max uboot
Hi Bin, After adding CONFIG_SFI=y to the kernel config, I was able to see both CPUs in the kernel boot, but now the kernel hangs at boot time. It did not hang when CONFIG_SFI was not set. and if I boot the CONFIG_SFI=y kernel using EFI BIOS it does not hang either. I have repeated the test a few times with the same results each time. I have enclosed the kernel boot log if you can see anything, or have any more suggestions.

Re: [U-Boot] MinnowBoard Max uboot
Hi Simon, I have just picked up u-boot-2015.07-rc2 with your support for multiple CPUs on the minnowboard max. I can see using the uboot cpu list command that both CPUs now show up. But the kernel does not see 2 CPUs in /proc/cpuinfo. If I boot the same kernel using an EFI BIOS I do see 2 CPUs in /proc/cpuinfo. Is there some uboot to kernel hand off I do not have configured properly ? I am not sure how the number of CPUs gets transferred from the boot to the kernel. Thanks for any input you may have.
