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 has "Master DMA Mode Tx Buffer Base Address[39:32](0x60)"
and "Master DMA Mode Rx Buffer Base Address[39:32](0x64)"
registers to save the high part physical address of Tx/Rx
buffer address for master mode.

It has "Slave DMA Mode Tx Buffer Base Address[39:32](0x68)" and
"Slave DMA Mode Rx Buffer Base Address[39:32](0x6C)" registers
to save the high part physical address of Tx/Rx buffer address
for slave mode.

Ex: Tx buffer address for master mode [39:0]
The "Master DMA Mode Tx Buffer Base Address[39:32](0x60)"
bits [7:0] which corresponds the bits [39:32] of the 64 bits address of
the Tx buffer address.
The "Master DMA Mode Tx Buffer Base Address(0x30)" bits [31:0]
which corresponds the bits [31:0] of the 64 bits address
of the Tx buffer address.

Introduce a new has_dma64 class attribute and new registers for the
new mode to support DMA 64 bits dram address.
Update new mode register number to 28.

The aspeed_i2c_bus_vmstate is changed again and
version is not increased because it was done earlier in the same series.

hw/i2c/aspeed: Fix old reg slave receive

I think when Klaus ported his slave mode changes from the original patch
series to the rewritten I2C module, he changed the behavior of the first
byte that is received by the slave device.

What's supposed to happen is that the AspeedI2CBus's slave device's
i2c_event callback should run, and if the event is "send_async", then it
should populate the byte buffer with the 8-bit I2C address that is being
sent to. Since we only support "send_async", the lowest bit should
always be 0 (indicating that the master is requesting to send data).

This is the code Klaus had previously, for reference. [1]

switch (event) {
case I2C_START_SEND:
bus->buf = bus->dev_addr << 1;

bus->buf &= I2CD_BYTE_BUF_RX_MASK;
bus->buf <<= I2CD_BYTE_BUF_RX_SHIFT;

bus->intr_status |= (I2CD_INTR_SLAVE_ADDR_RX_MATCH | I2CD_INTR_RX_DONE);
aspeed_i2c_set_state(bus, I2CD_STXD);

break;

hw/i2c/aspeed: Add new-registers DMA slave mode RX support

This commit adds support for DMA RX in slave mode while using the new
register set in the AST2600 and AST1030. This patch also pretty much
assumes packet mode is enabled, I'm not sure if this will work in DMA
step mode.

This is particularly useful for testing IPMB exchanges between Zephyr
and external devices, which requires multi-master I2C support and DMA in
the new register mode, because the Zephyr drivers from Aspeed use DMA in
the new mode by default. The Zephyr drivers are also using packet mode.

The typical sequence of events for receiving data in DMA slave + packet
mode is that the Zephyr firmware will configure the slave address
register with an address to receive on and configure the bus's function
control register to enable master mode and slave mode simultaneously at
startup, before any transfers are initiated.

RX DMA is enabled in the slave mode command register, and the slave RX
DMA buffer address and slave RX DMA buffer length are set. TX DMA is not
covered in this patch.

When the Aspeed I2C controller receives data from some other I2C master,
it will reset the I2CS_DMA_LEN RX_LEN value to zero, then buffer
incoming data in the RX DMA buffer while incrementing the I2CC_DMA_ADDR
address counter and decrementing the I2CC_DMA_LEN counter. It will also
update the I2CS_DMA_LEN RX_LEN value along the way.

Once all the data has been received, the bus controller will raise an
interrupt indicating a packet command was completed, the slave address
matched, a normal stop condition was seen, and the transfer was an RX
operation.

If the master sent a NACK instead of a normal stop condition, or the
transfer timed out, then a slightly different set of interrupt status
values would be set. Those conditions are not handled in this commit.

The Zephyr firmware then collects data from the RX DMA buffer and clears
the status register by writing the PKT_MODE_EN bit to the status
register. In packet mode, clearing the packet mode interrupt enable bit
also clears most of the other interrupt bits automatically (except for a
few bits above it).

Note: if the master transmit or receive functions were in use
simultaneously with the slave mode receive functionality, then the
master mode functions may have raised the interrupt line for the bus
before the DMA slave transfer is complete. It's important to have the
slave's interrupt status register clear throughout the receive
operation, and if the slave attempts to raise the interrupt before the
master interrupt status is cleared, then it needs to re-raise the
interrupt once the master interrupt status is cleared. (And vice-versa).
That's why in this commit, when the master interrupt status is cleared
and the interrupt line is lowered, we call the slave interrupt _raise_
function, to see if the interrupt was pending. (And again, vice-versa).

hw/i2c/aspeed: add slave device in old register mode

Add slave mode functionality for the Aspeed I2C controller in old
register mode. This is implemented by realizing an I2C slave device
owned by the I2C controller and attached to its own bus.

The I2C slave device only implements asynchronous sends on the bus, so
slaves not supporting that will not be able to communicate with it.

The model could be more precise to take into account all fields but
since the Linux driver is masking the register value being set, it
should be fine. See commit 3fb2e2aeafb2 ("i2c: aspeed: disable
