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.

dm: blk: add a device-probe hook for scanning disk partitions

2022-04-23T20:05:41+00:00

Now that all the block device drivers have enable a probe hook, we will
call part_create_block_devices() to enumerate all the partitions and
create associated udevices when a block device is detected.

block: ide: call device_probe() after scanning

2022-04-09T19:06:31+00:00

Every time an ide bus/port is scanned and a new device is detected,
we want to call device_probe() as it will give us a chance to run
additional post-processings for some purposes.

In particular, support for creating partitions on a device will be added.

dm: blk: Expand iteration and add tests

2022-04-06T18:03:17+00:00

Add some functions which support iteration before probing. Also add tests
for the functions.

disk: Add an option for partitions in SPL

In some cases we do not want to enable partition support in SPL. Add an
option to allow this.

sandbox: Open host file for read-only access if needed

2022-03-19T01:24:24+00:00

Some files cannot be written but read-only access is still useful for
tests. Add a fallback to read-only access when needed.

This is useful in CI when opening a large data file provided by docker,
where read/write access would result in copying the file, thus needing
a lot of extra disk space.
