[Qemu-devel] [PATCH 0/2] device_tree: add qemu_devtree_setprop_sized_cells()

[Peter Maydell]

These patches add a new function qemu_devtree_setprop_sized_cells()
to device_tree.c and use it in arm/boot.c.

We already have a qemu_devtree_setprop_cells() which sets a dtb
property to an array of cells whose values are specified by varargs.
However for the fairly common case of setting a property to a list
of addresses or of address,size pairs the number of cells used by
each element in the list depends on the parent's #address-cells
and #size-cells properties. To make this easier we provide an analogous
qemu_devtree_setprop_sized_cells() function which allows the number
of cells used by each element to be specified.

The arm/boot.c use is fairly straightforward; I also have some
virtio related patches brewing which are going to need to use this
to set their 'regs' property values. I figured it was probably better
to send this out for review now rather than wait for those, though.

The arm/boot bit of the patch depends (textually at least) on
http://patchwork.ozlabs.org/patch/251377/
  (arm/boot: Free dtb blob memory after use); it will apply cleanly
to git://git.linaro.org/people/pmaydell/qemu-arm.git arm-devs.next.
