[PATCH v2 00/30] hw/arm/raspi: Dynamically create machines based on the board revision

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Hi,

These patches simplify adding the raspi0/raspi1/raspi4 boards.

Igor has been working in his "refactor main RAM allocation to use
hostmem backend" series, and now v4 [1] is almost reviewed.

His raspi patch [2] clashes with my work, Since it is easier for
him to apply his on top of mine, I am sending these patches first.

Only the 4 first patches matter regarding Igor's refactor, to
include "Extract the RAM size from the board revision" which
should solve the problem he has to fix in [2].

I finally finished the SoC code, so can add the raspi0/1.
Avocado tests also include to demostrate the boards work.
I will probably move the raspi tests out of boot_linux_console.py,
but that is another series.

Latest patches NOTFORMERGE are mostly to justify this refactor,
like the raspi0 and 1, it is easy to add a new soc/board.
However other bcm peripherals patches need to get merged first
(on the list but old so I need to rebase/repost them).

Please review, at least up to patch 21 (before the tests).

Phil.
