Hi Maxim,

I've tried this series on my imx8mm-venice boards and find that basic
ping/dhcp/tftp breaks:
u-boot=> net list
eth0 : ethernet at 30be0000 00:d0:12:78:f8:01 active
u-boot=> setenv ipaddr 192.168.1.1
u-boot=> ping 192.168.1.146
eth0: ethernet at 30be0000 00:d0:12:78:f8:01 active
Using ethernet at 30be0000 device
pinging addr: 192.168.1.146
ping_tmo: ping failed; host 192.168.1.146 is not alive
u-boot=> dhcp
init already done for ethernet at 30be0000
dhcp_tmo 20/20
dhcp_tmo 19/20
dhcp_tmo 18/20
dhcp_tmo 17/20
dhcp_tmo 16/20
dhcp_tmo 15/20
dhcp_tmo 14/20
dhcp_tmo 13/20
dhcp_tmo 12/20
dhcp_tmo 11/20
dhcp_tmo 10/20
dhcp_tmo 9/20
dhcp_tmo 8/20
dhcp_tmo 7/20
dhcp_tmo 6/20
dhcp_tmo 5/20
dhcp_tmo 4/20
dhcp_tmo 3/20
dhcp_tmo 2/20
dhcp_tmo 1/20
dhcp_tmo 0/20
DHCP client timeout
u-boot=> tftpboot $loadaddr venice/Image
init already done for ethernet at 30be0000
TFTP from server 192.168.1.146; our IP address is 192.168.1.1
Filename 'venice/Image'.
Load address: 0x48200000
Loading:
^ cntl-c after a minute or so of no output

Is there some basic config here that I may have wrong?

Also, while trying to see if I can determine where things broke I
noticed there is build breakage starting with 'net/lwip: integrate
lwIP library'
In file included from net/lwip/lwip-external/src/core/init.c:38:
./net/lwip/lwip-external/src/include/lwip/opt.h:51:10: fatal error: lwipopts.h:

      |          ^~~~~~~~~~~~
compilation terminated.

We need to make sure that none of the patches within your series break
basic compilation or it makes it difficult for people to bisect
issues.

Best regards,

Tim
