hello,i am using u-boot on powerpc qemu,my u-boot version is
u-boot-2016.01-rc2,i make uboot as below:
cd u-boot-2016.01-rc2
make clean
make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- qemu-ppce500_defconfig
make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu-
then ,t execute u-boot bay qemu as below:
qemu-system-ppc -M ppce500 -serial stdio -kernel u-boot -m 1024
uboot show some msg as below:

Because you didn't specify any emulated NIC in qemu command line.
Here's a link maybe you can refer:
https://www.suse.com/documentation/sles11/book_kvm/data/cha_qemu_running_networking.html
See the "Defining a Network Interface Card" section. The commonly
used model with U-Boot should be e1000 or rtl8139 (rtl8139 is
not converted to driver model though)

This is because e1000 pci configuration space is not properly programmed:
=> pci
Scanning PCI devices on bus 0
BusDevFun VendorId DeviceId Device Class Sub-Class
_____________________________________________________________
00.01.00 0x8086 0x100e Network controller 0x00
=> pci display 00.01.00
00000000: 100e8086 00000006 02000003 00000008
00000010: 00000000 00000001 00000000 00000000
00000020: 00000000 00000000 00000000 11001af4
00000030: 00040000 00000000 00000000 00000100
=>
Look at offset 0x10 which is BAR0, all zero is not a valid pci address which
causes the error when e1000 driver tries to remap it.
It seems U-boot writes address larger than 4GB (the physical address
is taken from device tree prepared by qemu and the board enables 36bit
addressing) to bar0 while e1000 only supports 32bit pci bar, which
result in 0 being written and the upper 32bit address is omitted.
So include the maintainer here for more info.
Note there is another bug in e1000 driver that will
hang in BE target, I will send a separate patch to
fix that.
