[Qemu-devel] [PATCH 0/7] ARM boards: don't prematurely explode QEMUMachineInitArgs

[Qemu-devel] [PATCH 0/7] ARM boards: don't prematurely explode QEMUMachineInitArgs

[Peter Maydell]

A lot of the ARM board models follow the pattern of having a
single common init function which is called with various
parameters from the QEMUMachine init function for several board
model variants. The change to QEMUMachineInitArgs in commit 5f072e
took the fairly mechanical approach of splitting the QEMUMachineInitArgs
fields out in each variant's init function to pass to an unchanged
common init function. This is a bit repetitive, so clean them up
to just pass the QEMUMachineInitArgs directly to the common
function instead.

A quick grep finds similar cleanup opportunities in
