ASPEED AST2700 SOC is a 64 bits quad core CPUs (Cortex-a35)
And the base address of dram is "0x4 00000000" which
is 64bits address.
It have "Normal Priority Transmit Ring Base Address Register High(0x17C)",
"High Priority Transmit Ring Base Address Register High(0x184)" and
"Receive Ring Base Address Register High(0x18C)" to save the high part physical
address of descriptor manager.
Ex: TX descriptor manager address [34:0]
The "Normal Priority Transmit Ring Base Address Register High(0x17C)"
bits [2:0] which corresponds the bits [34:32] of the 64 bits address of
the TX ring buffer address.
The "Normal Priority Transmit Ring Base Address Register(0x20)" bits [31:0]
which corresponds the bits [31:0] of the 64 bits address
of the TX ring buffer address.
Besides, it have "TXDES 2 and 3" and "RXDES 2 and 3"
to save the high part physical address of packet buffer.
Ex: TX packet buffer address [34:0]
The "TXDES 2" bits [18:16] which corresponds the bits [34:32]
of the 64 bits address of the TX packet buffer address
and "TXDES 3" bits [31:0] which corresponds the bits [31:0]
of the 64 bits address of the TX packet buffer address.
Update TX/RX ring and descriptor data type to uint64_t
and supports TX/RX ring, descriptor and packet buffers
64 bits address for all ASPEED SOCs models.
Incrementing the version of vmstate to 2.

This looks OK overall. However it is exposing a new set of
registers that were not available on the previous implementation.
To expose the new regs, we could introduce either a new object
attribute and property or a new class and class attribute. With
this attribute, the realize handler could instantiate a new memory
region and map it on top of the current one. The new memop handlers
would implement the FTGMAC100_*_HIGH regs. We could avoid the extra
memory region by testing the new attribute in the existing memop
handlers but I think it would be cleaner to have an extra region.
Thanks,
C.
