EEPROM's are a form of non-volatile memory. After power-cycling an EEPROM,
I would expect the I2C state machine to be reset to default values, but I
wouldn't really expect the memory to change at all.
The current implementation of the at24c EEPROM resets its internal memory on
reset. This matches the specification in docs/devel/reset.rst:
Cold reset is supported by every resettable object. In QEMU, it means we reset
to the initial state corresponding to the start of QEMU; this might differ
from what is a real hardware cold reset. It differs from other resets (like
warm or bus resets) which may keep certain parts untouched.
But differs from my intuition. For example, if someone writes some information
to an EEPROM, then AC power cycles their board, they would expect the EEPROM to
retain that information. It's very useful to be able to test things like this
in QEMU as well, to verify software instrumentation like determining the cause
of a reboot.

With the `size += 4` before the call to `crc32`, the CRC calculation
would overrun the buffer. Size is used in the while loop starting on
line 1009 to determine how much data to write back, with the last
four bytes coming from `crc_ptr`, so do need to increase it, but should
do this after the computation.
I'm unsure why this use of uninitialized memory in the CRC doesn't
result in CRC errors, but it seems clear to me that it should not be
included in the calculation.

supermicrox11-bmc is configured with ast2400-a1 SoC. This does not match
the Supermicro documentation for X11 BMCs, and it does not match the
devicetree file in the Linux kernel.
As it turns out, some Supermicro X11 motherboards use AST2400 SoCs,
while others use AST2500.
Introduce new machine type supermicrox11-spi-bmc with AST2500 SoC
to match the devicetree description in the Linux kernel. Hardware
configuration details for this machine type are guesswork and taken
from defaults as well as from the Linux kernel devicetree file.
The new machine type was tested with aspeed-bmc-supermicro-x11spi.dts
from the Linux kernel and with Linux versions 6.0.3 and 6.1-rc2.
Linux booted successfully from initrd and from both SPI interfaces.
Ethernet interfaces were confirmed to be operational.

Make a copy of wout_x1 before modifying it, as wout_x1_P
emphasizing that it operates on the out/out2 pair. The insns
that use x1_P are data movement that will not change to Int128.
