To quote the author:
This series adds a new errors-only pylint check and adds it to the CI
systems.

It also fixes the current errors in the U-Boot Python code, disabling
errors where it seems necessary.

A small patch to buildman allows it to build sandbox without any changes

in order to augment the DTB for different board and LCD types.

We then add a custom ft_board_setup() callback that will inspect
the DTB and patch it using the stored LCD type. At this point
we know which product we are dealing with, so using the passed

We patch the Codina, Skomer and Kyle DTBs to use the right
LCD type as passed in lcdtype from the SBL.

This also creates an infrastructure for handling any other

efi_loader: fix uefi secure boot with intermediate certs

The general rule of accepting or rejecting an image is
 1. Is the sha256 of the image in dbx
 2. Is the image signed with a certificate that's found in db and
    not in dbx
 3. The image carries a cert which is signed by a cert in db (and
    not in dbx) and the image can be verified against the former
 4. Is the sha256 of the image in db

For example SHIM is signed by "CN=Microsoft Windows UEFI Driver Publisher",
which is issued by "CN=Microsoft Corporation UEFI CA 2011", which in it's
turn is issued by "CN=Microsoft Corporation Third Party Marketplace Root".
The latter is a self-signed CA certificate and with our current implementation
allows shim to execute if we insert it in db.

However it's the CA cert in the middle of the chain which usually ends up
in the system's db.  pkcs7_verify_one() might or might not return the root
certificate for a given chain.  But when verifying executables in UEFI,  the
trust anchor can be in the middle of the chain, as long as that certificate
is present in db.  Currently we only allow this check on self-signed
certificates,  so let's remove that check and allow all certs to try a
match an entry in db.

Open questions:
- Does this break any aspect of variable authentication since

cmd: clk: replace clk_lookup by uclass_get_device_by_name

The function clk_lookup can be replaced by a direct call
to uclass_get_device_by_name for UCLASS_CLK.

This patch removes duplicated codes by the generic DM API and avoids
issue in clk_lookup because result of uclass_get_device wasn't tested;
when ret < 0, dev = NULL and dev->name is invalid, the next function
call strcmp(name, dev->name) causes a crash.

Binman keeps track of positions of each entry in the final image, but
currently this data is wrong for things included in FIT entries,
especially since a previous patch makes FIT a subclass of Section and
inherit its implementation.

There are three ways to put data into a FIT image. It can be directly
included as a "data" property, or it can be external to the FIT image
represented by an offset-size pair of properties. This external offset
is either "data-position" from the start of the FIT or "data-offset"
from the end of the FIT, and the size is "data-size" for both. However,
binman doesn't use the "data-offset" method while building FIT entries.

According to the Section docstring, its subclasses should calculate and
set the correct offsets and sizes in SetImagePos() method. Do this for
