Hello,
I could not boot Raspbian on QEMU's raspi emulation and I'm not sure why
it fails. So question is if this is supposed to work or am I doing
something wrong or any clues what may be missing? I'm trying with this
command line with v3.1.0-rc3:
qemu-system-arm -M raspi2 -serial stdio \
-kernel rpi-kernel7.img -dtb bcm2709-rpi-2-b.dtb \
-append "rw earlyprintk loglevel=8 console=ttyAMA0,115200
dwc_otg.lpm_enable=0 root=/dev/mmcblk0p2" \
-drive file=2018-10-09-raspbian-stretch-lite.img,format=raw,if=sd
Kernel starts to boot, I see raspberries on the guest screen and log
output to serial:

Tried with your v3.1.0-local branch but got same results (does not find
mmcblk0 on raspi2, nothing on raspi3) so probably it's not one of the
patches in your tree that's missing.
multi_v7_defconfig.
Then maybe it's your kernel config that's different? Do you have compiled
kernels available that I could try?
Shouldn't be, but I attached my configuration. This time with v4.14.84 and
"make ARCH-arm savedefconfig" after building the image. The output is
identical
to "make ARCH=arm multi_v7_defconfig; make ARCH=arm savedefconfig".
Oh, and here is my qemu configuration.
--disable-user --disable-gnutls --disable-docs \
--disable-nettle --disable-gcrypt --disable-vnc-png \
--disable-xen --disable-xen-pci-passthrough \
--enable-debug --disable-strip
That should not make a difference either, but who knows.
Just to be sure, I copied a kernel and a root file system
to http://server.roeck-us.net/qemu/arm-raspi2/
