Florent Kermarrec f943a395f6 liteeth_gen: Add DHCP support and demonstrate it on udp_usp_gth_sgmii.yml config. 2023-07-03 18:07:36 +02:00
Florent Kermarrec 4afd325fc6 core/dhcp: Shorten offered_ip_address to ip_address. 2023-07-03 18:06:48 +02:00
Florent Kermarrec 7a988bee22 core: Add initial/minimal DHCP support to hardware stack. 
Ex of use in a  SoC that issues a DHCP request per second:

from liteeth.core.dhcp import LiteEthDHCP

from migen.genlib.misc import WaitTimer

# Signals.
ip_address  = Signal(32)
mac_address = Signal(48, reset=0x10e2d5000001)

# Request Timer.
self.dhcp_timer = dhcp_timer = WaitTimer(int(sys_clk_freq/2))
self.comb += self.dhcp_timer.wait.eq(~self.dhcp_timer.done)

# DHCP.
dhcp_port = self.ethcore_etherbone.udp.crossbar.get_port(68, dw=32, cd="sys")
self.dhcp = dhcp = LiteEthDHCP(udp_port=dhcp_port, sys_clk_freq=sys_clk_freq)
self.comb += [
    dhcp.start.eq(self.dhcp_timer.done),
    dhcp.mac_address.eq(mac_address),
]

self.sync += [
    If(dhcp.done,
        ip_address.eq(dhcp.offered_ip_address)
    )
]

Arne Jansen e83fd55fe8 add tx_write_only flag 
This can save some resources in case reading the tx buffer is not needed.
It also makes it easier for synthesis to infer BRAM, tested on Spartan6.
