[PATCH v2 00/20] ppc: QOM'ify 405 board |

Hello,
Here is large series QOM'ifying the PPC405 board. It introduces a new
generic machine and SoC models, converts the current device models to
QOM and populates the SoC. The process is quite mechanical without too
much issues to handle. The noisy part is the initial patch introducing
the SoC realize routine.
What's left ?
* The DCR read/writre handlers are attached in table to the CPU
instance. We could probably rework the whole with a specific address
space and memory regions handling the implemented registers. I don't
think this is necessary.
* the SDRAM mappings are very baroque and certainly could be simplified.
I think we should QOMify the ppc440 machines before addressing this
part.
Thanks,
C.
Changes in v2 :
- docs/about/removed-features.rst update
- Fix compile breakage (uic)
- Fix CPU reset, which breaking u-boot boot
- Changed prefix of memory regions to "ppc405"
- Reduced the number of RAM banks to 1. Second was a dummy one to
please ppc405ep_init()
