[Qemu-devel] [PATCH 00/10] vexpress: implement more SYS_CFG registers (feat. qdev property arrays)

[Peter Maydell]

This patchset fixes a number of warnings produced by Linux 3.8
on the vexpress boards resulting from newer kernels prodding
more of the SYS_CFG register operations.

Since some of the newly implemented functions expose voltage
and oscillator settings which vary in number and value between
vexpress daughterboards, these are exposed as qdev properties.
The patchset therefore includes implementation of support for
(variable length) qdev array properties. These work by
initially exposing a "len-arrayname" property; when the device
user sets this property to the desired array length, a further
set of dynamic "arrayname[0]", "arrayname[1]", etc properties
are created so the array elements can be set.

Patches 1-5 are some preliminary cleanup and implementation of
bits of SYS_CFG that don't require the property arrays.
Patch 6 implements the arrays themselves.
Patches 7,8 and 9,10 are paired patches which each add an array
property to to the arm_sysctl code and then use it.
