here as well.

Merge branch '2022-04-25-initial-implementation-of-stdboot'

2022-04-25T20:02:27+00:00

To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.

It introduces the following concepts:

   - bootdev - a device which can hold a distro
   - bootmeth - a method to scan a bootdev to find bootflows (owned by
                U-Boot)
   - bootflow - a description of how to boot (owned by the distro)

This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.

With this we can boot on a Raspberry Pi 3 with just one command:

   bootflow scan -lb

which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.

With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.

- Assorted binman updates, and add Alper as a maintainer, after talking
  with Simon.

binman: don't import deprecated distutils package

2022-04-25T14:11:05+00:00

'make tests' fails on Ubuntu 22.04 with:

binman: ./tools/binman/binman:12: DeprecationWarning:
The distutils package is deprecated and slated for removal in Python 3.12.
Use setuptools or check PEP 632 for potential alternatives
  from distutils.sysconfig import get_python_lib
./tools/binman/binman:12: DeprecationWarning:
The distutils.sysconfig module is deprecated, use sysconfig instead
  from distutils.sysconfig import get_python_lib

AssertionError: 0 != 468

As we don't use Ubuntu 16.04 for our CI anymore drop the import.

MAINTAINERS: Add Alper as a binman maintainer

2022-04-25T14:11:05+00:00

I ended up learning most of binman internals while trying to add a few
features to it, and I recently started reviewing binman series that
would not affect me personally. I'll keep working on it and try to do
more reviews.

Add myself as a maintainer for binman.

binman: Refuse to replace sections for now

2022-04-25T14:11:05+00:00

Binman interfaces allow attempts to replace any entry in the image with
arbitrary data. When trying to replace sections, the changes in the
section entry's data are not propagated to its child entries. This,
combined with how sections rebuild their contents from its children,
eventually causes the replaced contents to be silently overwritten by
rebuilt contents equivalent to the original data.

Add a simple test for replacing a section that is currently failing due
to this behaviour, and mark it as an expected failure. Also, raise an
error when replacing a section instead of silently pretending it was
replaced.

binman: Test replacing non-section entries in FIT subsections

2022-04-25T14:11:05+00:00

A previous patch fixes binman to correctly extract FIT subentries. This
makes it easier to test replacing these entries as we can write tests
using an existing helper function that relies on extracting the replaced
entry.

Add tests that replace leaf entries in FIT subsections with data of
various sizes. Replacing the subsections or the whole FIT section does
not work yet due to the section contents being re-built from unreplaced
subentries' data.

binman: Create FIT subentries in the FIT section, not its parent

2022-04-25T14:11:05+00:00

When reading images from a file, each entry's data is read from its
parent section as specified in the Entry.Create() call that created it.
The FIT entry type has been creating its subentries under its parent
(their grandparent), as creating them under the FIT entry resulted in an
error until FIT was converted into a proper section.

FIT subentries have their offsets relative to the FIT section, and
reading those offsets in the parent section results in wrong data. The
subentries rightfully belong under the FIT entries, so create them
there. Add tests checking that we can extract the correct data for a FIT
entry and its subentries.
