This is the end of the QOMify series started by Cédric. This series
handles the SDRAM controller models to clean them up, QOMify and unify
them and at least partially clean up the mess that has accumulated
around these in the past. This includes the not yet merged patches
from the last series and new ones that change the DDR2 version used by
sam460ex.

v6: Split patch moving sdram controller models together into smaller steps
v5: Add functions the enable sdram controller and call it from boards
v4: address more review comments
v3: Fix patches that got squashed during rebase
v2: address some review comments and try to avoid compile problem with
gcc 12.2 (untested)

BALATON Zoltan (25):
  ppc440_bamboo: Remove unnecessary memsets
  ppc4xx: Introduce Ppc4xxSdramBank struct
  ppc4xx_sdram: Get rid of the init RAM hack
  ppc4xx: Use Ppc4xxSdramBank in ppc4xx_sdram_banks()
  ppc440_bamboo: Add missing 4 MiB valid memory size
  ppc4xx_sdram: Move size check to ppc4xx_sdram_init()
  ppc4xx_sdram: QOM'ify
  ppc4xx_sdram: Drop extra zeros for readability
  ppc440_sdram: Split off map/unmap of sdram banks for later reuse
  ppc440_sdram: Implement enable bit in the DDR2 SDRAM controller
  ppc440_sdram: Get rid of the init RAM hack
  ppc440_sdram: Rename local variable for readability
  ppc4xx_sdram: Rename functions to prevent name clashes
  ppc440_sdram: Move RAM size check to ppc440_sdram_init
  ppc440_sdram: QOM'ify
  ppc440_uc.c: Move some macros to ppc4xx.h
  ppc440_uc.c: Remove unneeded parenthesis
  ppc440_uc.c: Move DDR2 SDRAM controller model to ppc4xx_sdram.c
  ppc4xx_devs.c: Move DDR SDRAM controller model to ppc4xx_sdram.c
  ppc4xx_sdram: Move ppc4xx_sdram_banks() to ppc4xx_sdram.c
  ppc4xx_sdram: Use hwaddr for memory bank size
  ppc4xx_sdram: Rename local state variable for brevity
  ppc4xx_sdram: Generalise bank setup
  ppc4xx_sdram: Convert DDR SDRAM controller to new bank handling
  ppc4xx_sdram: Add errp parameter to ppc4xx_sdram_banks()

Zoltan,

I've started to push some patches to ppc-next. Patches 1-13 are already pushed
and I'm running tests on patches 14-17. Assuming everything is ok we'll be
left with patches 18-25 to work on.


Thanks,


Daniel

Zoltan,

Could we add you as a MAINTAINER of these files ? You know them well now.
At least the ppc44* ones.

Thanks,

C.

Patches 01-17 queued in ppc-next.

If a next version is needed you can resend just 18-25.

I may know some things now but I forget quickly :-) I already maintain the 
files I've written but don't really want to get cc-d on others. I read the 
list though and if I see something I can help with I'll try to do so like 
with this series. That's all I can commit to now, not taking other orphan 
files, so no thanks but I'll try to review what I can informally.

Regards,
BALATON Zoltan

Thanks. Hope somebody can review the remaining ones too. Patches 18-20 are 
just moving stuff to ppc4xx_sdram.c which are now in 3 patches for easier 
review with --color-moved, 21-22 and 25 are already reviewed by Philippe 
so only 23-24 need more attention.
