We previously stored the device tree at a 16MB alignment from the end of
memory (or 3GB). This means we need at least 16MB of memory to be able
to do this. We don't actually need the FDT to be 16MB aligned, so let's
drop it down to 2MB so that we can support systems with less memory,
while also allowing FDT size expansion.

This introduces a really basic PECI controller that responses to
commands by always setting the response code to success and then raising
an interrupt to indicate the command is done. This helps avoid getting
hit with constant errors if the driver continuously attempts to send a
command and keeps timing out.
The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC.
They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support
PECI 4.0, which includes more read/write buffer registers from 0x80 to
0xFC to support 64-byte mode.
This patch doesn't attempt to handle that, or to create a different
version of the controller for the different generations, since it's only
implementing functionality that is common to all generations.
The basic sequence of events is that the firmware will read and write to
various registers and then trigger a command by setting the FIRE bit in
the command register (similar to the I2C controller).
Then the firmware waits for an interrupt from the PECI controller,
expecting the interrupt status register to be filled in with info on
what happened. If the command was transmitted and received successfully,
then response codes from the host CPU will be found in the data buffer
registers.

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).

Add an asynchronous version of i2c_send() that requires the slave to
explicitly acknowledge on the bus with i2c_ack().
The current master must use the new i2c_start_send_async() to indicate
that it wants to do an asynchronous transfer. This allows the i2c core
to check if the target slave supports this or not. This approach relies
on adding a new enum i2c_event member, which is why a bunch of other
devices needs changes in their event handling switches.

I noticed i2c rx transfers were getting shortened to "1" on Zephyr. It
seems to be because the Zephyr i2c driver sets the RX DMA len with the
RX field write-enable bit set (bit 31) to avoid a read-modify-write. [1]
/* 0x1C : I2CM Master DMA Transfer Length Register */
I think we should be checking the write-enable bits on the incoming

the write-enable bits to the register array, actually.

Add a qdev gpio input in lasips2_init() by taking the existing lasips2_port_set_irq()
function, updating it accordingly and then renaming to lasips2_set_irq(). Use these
new qdev gpio inputs to wire up the PS2 keyboard and mouse devices.
At the same time set update_irq() and update_arg to NULL in ps2_kbd_init() and
ps2_mouse_init() to ensure that any accidental attempt to use the legacy update_irq()
function will cause a NULL pointer dereference.
