9444387838 net: Disable the format-extra-args warning
We will see warnings such as:
net/eth_common.c:57:61: warning: data argument not used by format string [-Wformat-extra-args]
        sprintf(enetvar, index ? "%s%daddr" : "%saddr", base_name, index);

With clang.  In this case we do not want to re-write our code to be less
compact as the above is intentional and readable.  Add a comment above
the disabling so that it's clear why we want that warning off.

bc6fc28b86 net: Optionally use pxe client arch from variable
The client architecture that we pass to a dhcp server depends on the target
payload that we want to execute. An EFI binary has a different client arch
than a legacy binary or a u-boot binary.

So let's parameterize the pxe client arch field to allow an override via
the distro script, so that our efi boot path can tell the dhcp server that
it's actually an efi firmware.

20898ea934 distro: Add efi pxe boot code
Now that we can expose network functionality to EFI applications,
the logical next step is to load them via pxe to execute them as
well.

This patch adds the necessary bits to the distro script to automatically
load and execute EFI payloads. It identifies the dhcp client as a uEFI
capable PXE client, hoping the server returns a tftp path to a workable
EFI binary that we can then execute.

To enable boards that don't come with a working device tree preloaded,
this patch also adds support to load a device tree from the /dtb directory
on the remote tftp server.

Add a new environment variable that directly sets the retry period for
BOOTP timeouts. If this new value is not set, the period is still derived
from the default number of retries, or from CONFIG_NET_RETRY_COUNT if
defined. When both the new variable is set and CONFIG_NET_RETRY_COUNT
