I am getting this on a Northstar 1 / BCM4708:

[ 0.143643] Setting up static identity map for 0x82a0 - 0x82d4
[ 0.189772] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
[ 0.189861] Brought up 2 CPUs
[ 0.198845] SMP: Total of 2 processors activated (3188.32 BogoMIPS).
[ 0.205446] CPU: WARNING: CPU(s) started in wrong/inconsistent modes
(primary CPU mode 0x13)
[ 0.214167] CPU: This may indicate a broken bootloader or firmware.
I assume that this is correct and the bootloader is just broken, it uses
this bootloader: "CFE for Foxconn Router version: v1.0.14", I haven't
noticed any problems, so it is ok for me.

On my 4708 SVK, I see the same issue
[ 0.090877] CPU: Testing write buffer coherency: ok
[ 0.091231] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[ 0.091377] Setting up static identity map for 0x82a0 - 0x82f8
[ 0.130146] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001
[ 0.130251] Brought up 2 CPUs
[ 0.130323] SMP: Total of 2 processors activated (3188.32 BogoMIPS).
[ 0.130345] CPU: WARNING: CPU(s) started in wrong/inconsistent modes (primary CPU mode 0x13)
[ 0.130374] CPU: This may indicate a broken bootloader or firmware.
I'll investigate it more and see if I can bottom out on the cause.
Thanks,

I looked at previous versions of this patch, and the issue appears to
be present there as well. I'm not sure why I didn't notice it before.
I don't think "fixing" CFE is an option. Should we investigate the
possibility of setting the CPU mode of CPU1 in the early_boot of
Linux?
