The function string_to_ip is already in net_utils, which is
compiled unconditionally, but ip_to_string is currently only
accessible if the legacy network stack is selected. This
commit puts ip_to_string in net_utils.c and removes it from the
legacy network code.

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.
-Check for port in the uri when transforming to legacy wget
syntax inside wget_with_dns.
-Move the check for CMD_DNS inside wget_with_dns.

Is the alignment required by the spec?

These are aligned members in a packed struct which might cause
alignment warnings.
Commit 7dfab398558 explains why.

sizeof(*ipv4dp) is usually preferred here

is this 4 or 6?

You can skip the void casts

That's ok, but we tend to do (void *)((uintptr_t) casts nowadays

Add EFI definitions for EFI_IP4_CONFIG2_PROTOCOL,
EFI_HTTP_SERVICE_BINDING_PROTOCOL, and EFI_HTTP_PROTOCOL.
According to UEFI spec 2.10.

Add the functions efi_net_set_addr and efi_net_get_addr to set
and get the ip address from efi code in a network agnostic way.
This could also go in net_common, or be compiled conditionally
for each network stack.

Add efi_dp_from_http to form a device path from HTTP. The
device path is the concatenation of the device path returned
by efi_dp_from_ipv4 together with an URI node and an END node.

We need some sanity checking here, since the server name is a user

Can you move this checking on top? You can avoid alloc/free buffers is

Set the device path of the efi boot device to an HTTP device path
(as formed by efi_dp_from_http) when the next boot stage is loaded
using wget (i.e., when wget is used with wget_info.set_bootdev=1).

Add network-stack agnostic way to send an http request and
parse http headers from efi drivers. This uses wget as a
backend and communicates with it via the struct wget_http_info
'wget_info'.
The function efi_net_do_request allocates a buffer on behalf of an
efi application using efi_alloc and passes it to wget to receive
the data. If the method is GET and the buffer is too small, it
re-allocates the buffer based on the last received Content-Length
header and tries again. If the method is HEAD it just issues one
request. So issuing a HEAD request (to update Content-Length) and
then a GET request is preferred but not required.
The function efi_net_parse_headers parses a raw buffer containing
an http header into an array of EFI specific 'http_header' structs.

Add an implementation of the EFI_IP4_CONFIG2_PROTOCOL. The protocol
is attached to the handle of the efi network device. This is the same
handle where snp and pxe are attached to.

Add an EFI HTTP driver. This commit implements the
EFI_HTTP_PROTOCOL and the EFI_HTTP_SERVICE_BINDING_PROTOCOL.
The latter is attached to the handle of th efi network
device. This is the same handle where snp, pxe, and ipconfig
are attached to.

Thank you for the suggestion. Not adding all the strings in SPL builds
makes sense.
Beyond this patch series some clean-up needed:
There are a lot of other #ifdefs which we probably should replace
separately from this series.
We have a symbol CONFIG_SPL_UUID but libuuid is built in SPL
irrespective of it.
In vsprintf we only check CONFIG_LIBUUID.
Best regards

Add a test for the EFI_IP4_CONFIG2_PROTOCOL. The test sets the ip
policy to static, adds an ip address, and then reads the current
ip address and checks for it to be the same as the one that was set.
