AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to the address which is beyond the ram size,
it would write the data to the "address % ram_size".
For example:
a. sdram base address "0x4 00000000"
b. sdram size 1 GiB
The available address range is from "0x4 00000000" to "0x4 3FFFFFFF".
If users write 0x12345678 to address "0x5 00000000",
the value of DRAM address 0 (base address 0x4 00000000) will be 0x12345678.
Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from "max_ram_size - ram_size" to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

The Aspeed SMC device model use to have a 'sdram_base' property. It
was removed by commit d177892d4a ("aspeed/smc: Remove unused
"sdram-base" property") because previous changes simplified the DMA
transaction model to use an offset in RAM and not the physical
address.
The AST2700 SoC has larger address space (64-bit) and a new register
DMA DRAM Side Address High Part (0x7C) is introduced to deal with the
high bits of the DMA address. To be able to compute the offset of the
DMA transaction, as done on the other SoCs, we will need to know where
the DRAM is mapped in the address space. Re-introduce a "dram-base"
property to hold this value.

In SNP, the hashes page designated with a specific metadata entry
published in AmdSev OVMF.
Therefore, if the user enabled kernel hashes (for measured direct boot),
QEMU should prepare the content of hashes table, and during the
processing of the metadata entry it copy the content into the designated
page and encrypt it.
Note that in SNP (unlike SEV and SEV-ES) the measurements is done in
whole 4KB pages. Therefore QEMU zeros the whole page that includes the
hashes table, and fills in the kernel hashes area in that page, and then
encrypts the whole page. The rest of the page is reserved for SEV
launch secrets which are not usable anyway on SNP.
If the user disabled kernel hashes, QEMU pre-validates the kernel hashes
page as a zero page.
