[Qemu-devel] [PATCH 01/17] hw/vexpress: Pass proc_id via VEDBoardInfo

[Peter Maydell <peter.maydell@linaro.org>]

Pass the daughterboard-specific proc_id property to the code that
creates the sysctl device via the VEDBoardInfo struct, rather than
by having the daughterboard init function write to a uint32_t*
argument. This is a cleaner way to pass the info around, and
is in line with the way we are going to handle voltage and
oscillator initialization.
