[Qemu-devel] [PATCH 0/6] add dumpdts ability to convert dtb to dts

[john.liuli]

From: Li Liu <address@hidden>

This patchset let qemu can convert dtb file to dts for two demands:

Some archtectures may generate the dtb file dynamically through
qemu device tree functions. So this let it's possiable to dump final
dtb to dts and save it as a reference.

For novices to debugging the issues caused by wrong dtb parameters.
It will be easy to check the dts directly without copying the
dtb which may be generated by 'dumpdtb' to the PC and dtc or fdtdump
it.

The outputed dts format is compatile with 'dtc -I dtb -O dts xxx.dtb'.
There's a new parameter 'dumpdts' which is similar to 'dumpdtb'. so try
it like '-machine dumpdts=/tmp/xxx.dts'.

Li Liu (6):
  device_tree.c: Introduce a function to check multiple strings for dts
  device_tree.c: dump three kind data types of dts to a file desciptor
  device_tree.c: Format a blob in memory as dts stream and dump to a
    file.
  device_tree.c: add the main function to analyse the parameter
    'dumpdts'
  machine: add 'dumpdts' parameter to 'machine' optslist.
  arm: Allow dumping generated dtb to dts file
