bootstd: Drop the bootdev-specific list of bootflows

2025-01-15T14:48:42+00:00

This list is only used by two functions, which can be updated to iterate
through the global list. Take this approach, which allows the bootdev
list to be dropped.

Overall this makes the code slightly more complicated, but will allow
moving the bootflow list into an alist

bootstd: Move bootflow-clearing to bootstd

2025-01-15T14:48:42+00:00

This relates to more than just the bootdev, since there is a global list
of bootflows. Move the function to the bootstd file and rename it.

bootstd: Add stub for bootdev_setup_for_sibling_blk()

2024-10-03T17:52:16+00:00

When bootstd is not enabled, bootdevs should not be set up. Add a
static inline function to see to this.

Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"

2023-12-13T16:51:53+00:00

To quote the author:

It would be useful to be able to boot an OS when CONFIG_CMDLINE is
disabled. This could allow reduced code size.

Standard boot provides a way to handle programmatic boot, without
scripts, so such a feature is possible. The main impediment is the
inability to use the booting features of U-Boot without a command line.
So the solution is to avoid passing command arguments and the like to
code in boot/

A similar process has taken place with filesystems, for example, where
we have (somewhat) separate Kconfig options for the filesystem commands
and the filesystems themselves.

This series starts the process of refactoring the bootm logic so that
it can be called from standard boot without using the command line.
Mostly it removes the use of argc, argv and cmdtbl from the internal
logic.

Some limited tidy-up is included, but this is kept to smaller patches,
rather than trying to remove all #ifdefs etc. Some function comments
are added, however.

A simple programmatic boot is provided as a starting point.

This work will likely take many series, so this is just the start.

Size growth with this series for firefly-rk3288 (Thumb2) is:

       arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0

This should be removed by:

   https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11

but it is not included in this series as it is already large enough.

No functional change is intended in this series.

Changes in v3:
- Add a panic if programmatic boot fails
- Drop RFC tag

Changes in v2:
- Add new patch to adjust position of unmap_sysmem() in boot_get_kernel()
- Add new patch to obtain command arguments
- Fix 'boot_find_os' typo
- Pass in the command name
- Use the command table to provide the command name, instead of "bootm"

bootstd: Add missing header file from bootdev.h

2023-12-13T16:51:24+00:00

Add a dm/uclass-id.h to the bootdev header file, since it uses
enum uclass_id

bootstd: Skip over bad device during bootflows scanning

2023-11-10T16:01:50+00:00

During bootstd scanning for bootdevs, if bootdev_hunt_drv() encounters
a device not found error (e.g. ENOENT), let it return a successful status
so that bootstd will continue scanning the next devices, not stopping
prematurely.

Background:

During scanning for bootflows, it's possible for bootstd to encounter a
faulty device controller. Also when the same u-boot is used for another
variant of the same board, some device controller such as SATA might
not exist.

I've found this issue while converting the Marvell Sheevaplug board to
use bootstd. This board has 2 variants, the original Sheevaplug has MMC and
USB only, but the later variant comes with USB, MMC, and eSATA ports. We
have been using the same u-boot (starting with CONFIG_IDE and later with DM
CONFIG_SATA) for both variants. This worked well with the old
envs-scripting booting scheme.

bootstd: Keep track of use of usb stop

2023-09-21T22:05:40+00:00

When 'usb stop' is run, doing 'bootflow scan' does not run the USB hunter
again so does not see any devices. Fix this by telling bootstd about the
state of USB.

bootstd: Rename bootdev_setup_sibling_blk()

2023-08-09T15:31:11+00:00

This name is a little confusing since it suggests that it sets up the
sibling block device. In fact it sets up a bootdev for it. Rename the
function to make this clearer.
