Waldemar Brodkorb 28d97609b2 configs/qemu: bump to the latest kernel version
Xtensa patches no longer required, the make target name changed
to Image. The Qemu binary for OpenRisc was renamed upstream.
I removed the x86->x86_64 symlink, independent files preferred.

(1) - Probably an endian issue with 8139 emulation/driver
(2) - There's a network interface, but enabling it in qemu fails
(3) - Kernel oops with 4.11.3 on boot
(4) - System is extremely slow with 4.11.3, needs further investigation
(5) - Qemu binary got renamed to qemu-system-or1k

Run the emulation with:
qemu-system-arm -M vexpress-a9 -smp 1 -m 256 -kernel output/images/zImage -dtb output/images/vexpress-v2p-ca9.dtb -drive file=output/images/rootfs.ext2,if=sd,format=raw -append "console=ttyAMA0,115200 root=/dev/mmcblk0" -serial stdio -net nic,model=lan9118 -net user
The login prompt will appear in the terminal that started Qemu. The
graphical window is the framebuffer.
If you want to emulate more cores change "-smp 1" to "-smp 2" for
dual-core or even "smp -4" for a quad-core configuration.
Tested with QEMU 2.9.0
