Subject: [PATCH 0/2] Add Axiado HCP network device model
This patchset introduces Axiado HCP network model for SoC AX3000
The HCP (Header and Crypto Processing) block is the substantial part of the series. It is the SoC's network complex, built around an Inside Secure SafeXcel EIP-197 packet engine that acts as bus master for all packet I/O over four command/result descriptor ring pairs. Five MACs are demultiplexed by an "application ID" tag carried in the EIP-96 input and output tokens. Only the packet datapath is modelled; the
EIP-197 cryptographic transforms are treated as pass-through, which is what the guest asks for when the block is used as a network interface.

Testing
-------
The user-mode network backend is required, so configure with libslirp enabled (it is auto-detected, and silently absent otherwise):
./configure --target-list=aarch64-softmmu -Dslirp=enabled
qemu-system-aarch64 \
-m 4G \
-machine axiado-scm3003 \
-device loader,file=u-boot.bin,addr=0x3C000000,cpu-num=0 \
-nographic \
-serial null \
-serial null \
-serial null \
-serial mon:stdio \
-drive if=sd,file=obmc-phosphor-image-evk-axiado-qemu.wic,format=raw \
-netdev user,id=net4,hostfwd=tcp::2222-:22 \
-global axiado-hcp.netdev4=net4 \
In the guest, bring the interface up with DHCP:
udhcpc -i eth0
Then from the host:
ssh -p 2222 root@127.0.0.1
With the unmodified vendor Linux driver, the guest:
- probes the HCP and brings eth0 up
- obtains an address over DHCP from the SLIRP backend
- resolves ARP and answers ping
- sustains an SSH session and completes an SCP transfer
Not modelled
------------
- EIP-197 cryptographic transforms. Descriptors are pass-through.
- PCS/SerDes behaviour. The guest configures these registers and never
reads them back, so writes are accepted and discarded; the link is
always reported up.
