Power11 core is same as Power10, use the existing functionalities to
introduce a Power11 chip and machine, with Power10 chip as parent of
Power11 chip, thus going through similar class_init paths

Please change introduce a new pnv_chip_quad_realize() routine taking an
extra type_name argument.

This should be using a versionned CPU "power11_vx.y".

Sure, can do it. But as it's called from 'pnv_chip_power10_realize',
might require a 'pnv_chip_power11_realize' function also, so it can pass
type_name as "power11" vs "power10".
Will do it.

I expanded the macro, to add '.class_base_init', as .class_base_init
will be run by QEMU during initialisation of any child classes also. And
I wanted to let QEMU call 'pnv_core_power10_class_init' when it
initialises 'power11' type.

Okay, then, should I have a 'pnv_core_power11_class_init' call
'pnv_core_power10_class_init' ?

Same, in that case, I can have a 'pnv_quad_power11_class_init' which
just calls 'pnv_quad_power10_class_init'.

Any comments ?

Yes, makes sense. Thanks Cédric.

Do the Power11 and Power10 processors have the same XSCOM and MMIO
