hw/hppa: Split out machine creation
Browse files Browse the repository at this point in the history 
This is a preparation patch to allow the creation of additional
hppa machine.

It splits out the creation of the machine into a
- machine_HP_common_init_cpus(), and a
- machine_HP_common_init_tail()
function.

This will allow to reuse the basic functions which are common to
all parisc machines.
