DB-88F6XXX kernel on 88F6281_A0 (GoFlex Net)

[Rasmus Liland]

Dear arm list,

I now almost managed to boot the DB-88F6XXX configuration on a 
Seagate GoFlex Net (Kirkwood 88F6281_A0), but not past clang 
announcement of the first nine dmesg lines before CPU 
announcement is being expected.

Based on sys/arm/mv/kirkwood/kirkwood.c, I am certain this board 
is supported. Attached is a log of the kernel being loaded in 
u-boot by running standard commands:

    dhcp
    tftpboot 500000 kernel.bin
    go 500000

The kernel was built based on an old 10/stable tree last checked 
out August 2016 using this standard procedure from the FreeBSD 
Wiki https://wiki.freebsd.org/FreeBSDMarvell:

    make buildworld TARGET_ARCH=arm
    make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F6XXX

I am not sure how to make it past the clang announcement, thus is 
it possible for anyone to point me in a fruitful direction?

/Rasmus
