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:

My version (https://github.com/groeck/qemu) seems to work, using
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?
Thank you,
