bootm: Create bootm_final() for pre-boot cleanup

2026-03-18T19:17:34+00:00

There are various functions which announce that booting is imminent and
do related preparation. Most of these are arch-specific.

In practice, most archs do a similar thing. It would be better to
have a common function, with perhaps some events for things that are
really arch- and board-specific.

Create a new bootm_final() function with the common pre-boot steps:
printing the "Starting kernel" message, recording bootstage data,
optionally writing bootstage to the FDT and printing a report, and
removing active devices.

Be careful to avoid using BIT() macros which are not available with host
tools.

Revert "Merge patch series "pxe: Allow extlinux booting without CMDLINE enabled""

2024-04-18T14:29:35+00:00

As reported by Jonas Karlman this series breaks booting on some AArch64
platforms with common use cases. For now the best path forward is to
revert the series.

This reverts commit 777c28460947371ada40868dc994dfe8537d7115, reversing
changes made to ab3453e7b12daef47b9e91da2a2a3d48615dc6fc.

Merge patch series "pxe: Allow extlinux booting without CMDLINE enabled"

2024-04-10T23:06:27+00:00

Simon Glass  says:

This series is the culmanation of the current line of refactoring
series. It adjusts pxe to call the booting functionality directly
rather than going through the command-line interface.

With this is is possible to boot using the extlinux bootmeth without
the command line enabled.

It also updates fastboot to do a similar thing.

bootm: Make cmdline optional with bootm_boot_start()

2024-04-10T23:04:25+00:00

Allow the default command line to be used when booting the OS. This is
needed by fastboot.

Merge patch series "Complete decoupling of zboot logic from commands"

2024-04-10T19:49:35+00:00

Simon Glass  says:

This series refactors the zboot code to allow it to be used with
CONFIG_COMMAND disabled.

A new zboot_run() function is used to boot a zimage.

x86: zboot: Tidy up the comment for zboot_run()

2024-04-10T19:49:16+00:00

The current use case (ChromeOS) is the uncommon case. Document how this
function is more normally used, where base is 0 and cmdline is NULL

x86: zboot: Rename zboot_start() to zboot_run()

2024-04-10T19:49:16+00:00

The term 'start' is used withint bootm and zboot to indicate the first
phase of booting an image.

Since zboot_start() does the whole boot, rename it to zboot_run() to
align with bootm_run() etc.

Fix a log message while we are here.

bootm: Create a function to run through the booti states

2023-12-21T21:07:52+00:00

In a few places, the booti command is used to handle a boot. We want
these to be done without needing CONFIG_CMDLINE, so add a new
booti_run() function to handle this.

So far this is not used.
