Eduardo Habkost db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Joel Stanley 14c179541b aspeed/sdmc: Perform memory training
This allows qemu to run the "normal" power on reset boot path through
u-boot, where the DDR is trained.

An enhancement would be to have the SCU bit stick across qemu reboots,
but be unset on initial boot.

Proper modelling would be to discard all writes to the phy setting regs
at offset 0x100 - 0x400 and to model the phy status regs at offset
0x400.

The status regs model would only need to account for offets 0x00,
0x50, 0x68 and 0x7c.

Igor Mammedov 533eb415df arm/aspeed: actually check RAM size
It's supposed that SOC will check if "-m" provided
RAM size is valid by setting "ram-size" property and
then board would read back valid (possibly corrected
value) to map RAM MemoryReging with valid size.
It isn't doing so, since check is called only
indirectly from
  aspeed_sdmc_reset()->asc->compute_conf()
or much later when guest writes to configuration
register.

So depending on "-m" value QEMU end-ups with a warning
and an invalid MemoryRegion size allocated and mapped.
(examples:
 -M ast2500-evb -m 1M
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-00000000800fffff (prio 0, ram): ram
      0000000080100000-00000000bfffffff (prio 0, i/o): max_ram
 -M ast2500-evb -m 3G
    0000000080000000-000000017ffffffe (prio 0, i/o): aspeed-ram-container
      0000000080000000-000000013fffffff (prio 0, ram): ram
      [DETECTED OVERFLOW!] 0000000140000000-00000000bfffffff (prio 0, i/o): max_ram
)
On top of that sdmc falls back and reports to guest
"default" size, it thinks machine should have.

This patch makes ram-size check actually work and
changes behavior from a warning later on during
machine reset to error_fatal at the moment SOC.ram-size
is set so user will have to fix RAM size on CLI
to start machine.

It also gets out of the way mutable ram-size logic,
so we could consolidate RAM allocation logic around
pre-allocated hostmem backend (supplied by user or
auto created by generic machine code depending on
supplied -m/mem-path/mem-prealloc options.

Joel Stanley d131bc28a6 aspeed_sdmc: Fix saved values
This fixes the intended protection of read-only values in the
configuration register. They were being always set to zero by mistake.

The read-only fields depend on the configured memory size of the system,
so they cannot be fixed at compile time. The most straight forward
option was to store them in the state structure.

Cédric Le Goater c2da8a8b90 ast2400: add a memory controller device model
The uboot in the previous release of the SDK was using a hardcoded
value for memory size. This is not true anymore, the value is now
retrieved from the memory controller.

Below is a model for this device, only supporting unlock and
configuration. Without it, we endup running a guest with 64MB, which
is a bit low nowdays. It uses a 'silicon-rev' property and ram_size to
build a default value. Some bits should be linked to SCU strapping
registers but it seems a bit complex to add for the current need.

The model is ready for the AST2500 SOC.
