[PATCH v4 00/24] ppc: QOM'ify 405 board

[Cédric Le Goater]

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.

Thanks,

C.

Changes in v4 :

 - Attempt to QOM'ify SDRAM controller, with 2 initialized banks at
   the SoC level 
 - Report errors to the user for invalid RAM config
 - Moved CPU reset in PPC405 model
 - user_creatable comments
 - Renamed FPGA device model
 - Various small cleanups

Changes in v3 :

 - New device model Ppc4xxDcrDeviceState
 - Removal of ppc4xx_mal_init(), ppc4xx_plb_init() and ppc405_ebc_init()
 - Fixes for some reset issues
 - Kept 2 RAM banks at the Soc level but only one is initialized.
 - Moved SRAM under the machine. It's not part of the SoC according
   to the 405 specs

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()
