PATCH 1/1 pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx, xps-ethernetlite-2.00.a' instead of 'xlnx, xps-ethernetlite-2.00.b'

For Linux upstream kernel (e.g. 3.17-rc7), the related compatible string 'xlnx,xps-ethernetlite-2.00.a' is supported, but 'b' is not supported, so change qemu dtb file to match kernel driver.

The related operation for qemu (after this patch):

yum install libvirt
yum install tunctl
tunctl -b
ip link set tap0 up
brctl addif virbr0 tap0

   ./configure
   make
   ./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \
     -kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \
     -no-reboot -append "console=ttyUL0,115200 doreboot" -nographic \
     -net nic,vlan=0,model=xlnx.xps-ethernetlite,macaddr=00:16:35:AF:94:00 \
     -net tap,vlan=0,ifname=tap0,script=no,downscript=no

in microblaze qemu bash (guest machine):

ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0 ifconfig eth0 up

Then can telnet 192.168.122.2 directly without password from the host machine.

The related operation for generating new dtb:

building Linux kernel firstly, then get dts tool "./scripts/dts/dts". "./scripts/dtc/dtc -I dtb -O dts -o ../work.dts ../qemu/petalogix-s3adsp1800.dtb" edit work.dts (replace 'xlnx,xps-ethernetlite-2.00.b') "./scripts/dtc/dtc -I dts -O dtb -o ..qemu/petalogix-s3adsp1800.dtb ../work.dts"

(Since I am not quite sure whether can read this patch or not, I put the related dtb file in attachment, please check, thanks).

GIT binary patch

Is it a binary-only file without source? Where it come from?

(it is not a simple question, eg, on Debian, binary files are disallowed (at least in main section)).

Thanks,

As far as I know, It is a hardware description file. Can convert it to dts format which is a text file, then can read and edit it, after finish, can convert it to dtb format again.

dts and dtb can convert with each other without any information lost. One tool for converting is "scripts/dts/dts" in upstream kernel (after finish building kernel).

So for me, we can also treat dtb file as open source file. It is integrated into qemu in 2009 (please "git log -p" to this file for more details).

Thanks.

Oh well. I don't like this patch to be lost, but I must admit I don't understand what's happening here. Applied to -trivial.

Thanks,

OK, thank you for your work. And I shall try to make another patch for qemu within this month.

Thanks.
