[Qemu-arm] [PATCH v5 00/14] arm: add ast2500 support

[Cédric Le Goater]

The AST2500 SoC being very close to the AST2400 SoC, the goal of the
changes below is to modify the existing platform palmetto-bmc and the
AST2400 SoC to take into account the small differences and avoid code
duplication. This is mostly inspired by the realview and the rpi2
platforms.

First patches rework the 'palmetto-bmc' platform and the 'ast2400' SoC
models to provide room to other platforms and SoCs which have a common
design. 

The last patches add support for the new AST2500 SoC in the required
controller (SDMC and SCU) and define a new platform for an Aspeed
evaluation board.


In v5, I have included a couple of improvements, suggested by Peter,
which let the Memory Controller decide if the setting of RAM size is
correct. The value is propagated to the controller through a property.

Thanks,

C.

Changes in v5 are :

  - fixed AspeedSoCClass definition which was using a DeviceState.
    This was coring on 32bit systems !!
  - sdmc improvements

Changes in v4 are :

  - used -M to detect file renames
  - fixed trailing comma in enums
  - fixed brackets around macro parameters
  - use '-1' for board ID to define device-tree-only board.

Changes in v3 are :

  - ast2400.c file rename
  - added a AspeedSocClass for each supported SoC
  - the silicon-rev and the cpu model are now constants at the SoC level 
  - more precise definition of the hardware strapping register 

Changes in v2 are :

  - palmetto_bmc.c file rename
  - SCU macros to define the hardware strapping register 

Cédric Le Goater (14):
  ast2400: rename the Aspeed SoC files to aspeed_soc
  ast2400: replace ast2400 with aspeed_soc
  aspeed-soc: provide a framework to add new SoCs
  palmetto-bmc: rename the Aspeed board file to aspeed.c
  palmetto-bmc: replace palmetto_bmc with aspeed
  palmetto-bmc: add board specific configuration
  hw/misc: use macros to define hw-strap1 register on the AST2400 Aspeed
    SoC
  aspeed: add a ast2500 SoC and support to the SCU and SDMC controllers
  arm: add support for an ast2500 evaluation board
  palmetto-bmc: remove extra no_sdcard assignement
  aspeed: calculate the RAM size bits at realize time
  aspeed: use error_report instead of LOG_GUEST_ERROR
  aspeed: add a ram_size property to the memory controller
  aspeed: allocate RAM after the memory controller has checked the size
