So, I was wrong for U-Boot. The ftgmac100 QEMU model is good enough 
to use the built-in TFTP server of the user mode network stack. We 
have a simple NCSI "echo" model for this stack. For the records, 
here is how to use it with QEMU.


Start the Aspeed guest with :

    -net nic,macaddr=C0:FF:EE:00:00:02,model=ftgmac100 -net user,id=netdev0,hostfwd=::2222-:22,hostname=vm2,tftp=/var/lib/tftpboot/

when under U-Boot, set the environment :

    setenv ethaddr C0:FF:EE:00:00:02
    setenv serverip 10.0.2.2
    setenv ipaddr 10.0.2.1

and tftpboot the image installed in /var/lib/tftpboot/

    tftp 0x48000000 fitimage.ast2400
    bootm 0x48000000

Cheers,

C.
