Re: [Qemu-trivial] [PATCH] pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx,

Subject: Re: [Qemu-trivial] [PATCH] pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx, xps-ethernetlite-2.00.a' instead of 'xlnx, xps-ethernetlite-2.00.b'

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).
