Enable the i82596 network chip which is included in the LASI
multi I/O chip. Since LASI has different start addresses on
the various machines, always initialize the LASI components
by their offsets.

i82596: Added core infrastructure and helper functions
As a part of GSOC 2025 I have done a massive rewrite of what was the
82596 NIC. This has been done to add the missing functionality according
to the 82596 Manual and making the code production ready.
This patch adds:
- comprehensive 82596 constants and configuration macros
- address translation for segmented/linear memory modes
- error recording and statistics tracking infrastructure
- CRC-16/32 calculation and appending functions
- CSMA/CD collision detection and backoff logic
- bus throttle timer framework
- enhanced reset with full state initialization
- receive_iov and polling support functions
- updated VMState for migration of all new fields
Note:
This patch primarily includes placeholder code.
To achieve full 82596 emulation, the complete 82596 patch series is
required. Nevertheless, QEMU is able to load and boot successfully with
this patch.

i82596: Implement enhanced TX/RX with packet queuing and filtering
In this patch I have added the following:
- Rewrote transmit path with CSMA/CD collision handling and retry logic
- Implemented flexible TX buffer descriptor (TBD) chain processing
- Rewrote receive path with packet filtering and monitor mode support
- Added RX packet queue for handling resource exhaustion
- Implemented queue flush timer and management
- Added RX state machine with proper state transitions
- Implemented packet filtering (unicast, broadcast, multicast, promiscuous)
- Added SCB RU_START enhancement to find usable RFDs
- Implemented dump command support
- Added bus throttle timer loading (LOAD_THROTTLE/LOAD_START commands)
- Enhanced signal_ca with proper initialization sequence
- Finally, adding self-test functionality
Note:
With this patch, and the previous ones in the patch series, we are able
to achive proper 82596 NIC emulation.

hw/sd/sdcard: Fix size check for backing block image
Alignment rules apply the the individual partitions (user, boot, later
on also RPMB) and depend both on the size of the image and the type of
the device. Up to and including 2GB, the power-of-2 rule applies to the
user data area. For larger images, multiples of 512 sectors must be used
for eMMC and multiples of 512K for SD-cards. Fix the check accordingly
and also detect if the image is too small to even hold the boot
partitions.

hw/sd/sdcard: Allow user creation of eMMCs
For testing eMMC-specific functionality (such as handling boot
partitions), it would be very useful to attach them to generic VMs such
as x86_64 via the sdhci-pci device:
...
-drive if=none,id=emmc-drive,file=emmc.img,format=raw \
-device sdhci-pci \
-device emmc,id=emmc0,drive=emmc-drive,boot-partition-size=1048576 \
...
While most eMMCs are soldered to boards, they can also be connected to
SD controllers with just a passive adapter, such as:
https://docs.radxa.com/en/accessories/emmc-to-usd
https://github.com/voltlog/emmc-wfbga153-microsd
The only change necessary to make the options above work is to avoid
disabling user_creatable, so do that. The SDHCI-PCI driver in the Linux
kernel already supports this just fine.

hw/sd/sdcard: Add basic support for RPMB partition
The Replay Protected Memory Block (RPMB) is available since eMMC 4.4
which has been obsoleted by 4.41. Therefore lift the provided
EXT_CSD_REV to 5 (4.41) and provide the basic logic to implement basic
support for it. This allows to set the authentication key, read the
write counter and authenticated perform data read and write requests.
Those aren't actually authenticated yet, support for that will be added
later.
The RPMB image needs to be added to backing block images after potential
boot partitions and before the user data. It's size is controlled by
the rpmb-partition-size property.
Also missing in this version (and actually not only for RPMB bits) is
persistence of registers that are supposed to survive power cycles. Most
prominent are the write counters or the authentication key. This feature
can be added later, e.g. by append a state structure to the backing
block image.

Remove unnecessary PCI configuration register initialization that was

- PCI_COMMAND register is already 0x00 by default, no need to override
- PCI_BASE_ADDRESS_0 registers are automatically set by pci_register_bar()
This aligns the code with the pattern used by other PCI audio devices
in QEMU (via-ac97, intel-hda, es1370) and removes 15 lines of dead code.
