net: Move some variables to net-common files

2026-01-15T10:09:28+00:00

Make some variables available to be used by either the legacy network
code or lwIP by moving them into the net-common files. This also allowed
removing a small number of duplicated variables from the lwIP code.

net: move net_state to net-common

2026-01-15T10:09:28+00:00

Move the net_state variable into common code so that it can be used by
either the legacy network code or lwIP. This is needed for porting
across the NFS support code for use with lwIP.

bootstd: make it possible to use tftp for netboot with standardboot

2025-10-24T19:47:50+00:00

Add the option to load the bootscript with the tftp command (static IP)
instead of the dhcp command (dynamic IP). For this a new function
tftpb_run similar to dhcp_run, is needed. The selection of which command
to use can be done with the ip_dyn environment variable, which can be
set to yes or no. The ip_dyn variable was chosen as it is already in use
on the imx platforms.
Also edit the bootstd doc.

net: make dhcp_run() common for NET and NET_LWIP

2025-10-22T12:28:33+00:00

There are currently two implementations of dhcp_run(): one in cmd/net.c
for NET and one in net/lwip/dhcp.c for NET_LWIP. There is no
justification for that. Therefore, move the NET version into
net/net-common.c to be used by both stacks, and drop the NET_LWIP
version which by the way does not look totally correct.

net: extract function net_sntp_set_rtc() from sntp_handler()

2025-07-08T09:07:37+00:00

Extract the code that sets the RTC clock from sntp_handler() in
net/sntp.c and make it a new function net_sntp_set_rtc() in
net/net-common.c. This will allow re-use with NET_LWIP.

According to [1] it is safe to assume that all devices have been
converted to DM_RTC so drop the useless code.

net: wget: let wget_with_dns work with dns disabled

2024-12-04T11:24:37+00:00

This was marked as TODO in the code:
 - Enable use of wget_with_dns even if CMD_DNS is disabled if
   the given uri has the ip address for the http server.
 - Move the check for CMD_DNS inside wget_with_dns.
 - Rename wget_with_dns to wget_do_request

net: wget: Add interface to issue wget_requests using wget_http_info

2024-11-16T20:35:05+00:00

Declare and define a global default struct wget_http_info
and an interface to issue wget requests providing a custom
struct wget_http_info. This code is common to legacy wget
and lwip wget. The idea is that the command wget should use
the default wget_http_info and other internal u-boot code
can call wget_request with their own wget_http_info struct.

net: split net into net{,-common,-legacy,-lwip}

2024-10-16T17:11:56+00:00

Make net.h a wrapper which includes net-common.h and either
net-legacy.h or net-lwip.h based on NET_LWIP. The function
copy_filename() can be useful when NET_LWIP is enabled, therefore
move it out of net/net.c which is built only when networking choice
is NET and create a new file net/net-common.c.
