x86: coreboot: Collect the address of the ACPI tables

2023-05-11T02:25:29+00:00

At present any ACPI tables created by prior-stage firmware are ignored.
It is useful to be able to view these in U-Boot.

Pick this up from the sysinfo tables and display it with the cbsysinfo
command. This allows the 'acpi list' command to work when booting from
coreboot.

Adjust the global_data condition so that acpi_start is available even if
table-generation is disabled.

include: Enable video related global data variable and splash at SPL

2023-04-24T19:37:45+00:00

To include video related global data variables and splash functions at
SPL and u-boot proper, use CONFIG_IS_ENABLED.

Replace CONFIG_CMD_BMP with CONFIG_BMP to enable splash_display function
at u-boot proper and SPL.

gpio: allow passing NULL to gpio_request_by_line_name() to search all gpio controllers

2023-03-30T19:09:59+00:00

The API is more convenient to use if one doesn't have to know upfront
which gpio controller has a line with the name one is searching for,
and arrange to look that device up somehow. Or implement this loop
oneself.

dm: Add support for handling old u-boot,dm- tags

2023-02-14T16:42:14+00:00

Add a CONFIG option to deal with this automatically, printing a warning
when U-Boot starts up. This can be useful if the device tree comes from
another project.

We will maintain this through the 2023.07 release, providing 6 months
for people to notice.

gpio: Get rid of gpio_hog_probe_all()

2023-01-12T19:06:16+00:00

The gpio_hog_probe_all() functionality can be perfectly well replaced by
DM_FLAG_PROBE_AFTER_BIND DM flag, which would trigger .probe() callback
of each GPIO hog driver instance after .bind() and thus configure the
hogged GPIO accordingly.

watchdog: Drop GD_FLG_WDT_READY as it's not used any more

2022-11-22T07:56:26+00:00

Since commit c2fd0ca1a822
("watchdog: Integrate watchdog triggering into the cyclic framework")
GD_FLG_WDT_READY has become write-only. This patch now removes this
flag completely.

The vacant spot in gd_flags is filled with the newly introduced
GD_FLG_CYCLIC_RUNNING flag.

cyclic: get rid of cyclic_init()

2022-11-02T07:42:03+00:00

Currently, we must call cyclic_init() at some point before
cyclic_register() becomes possible. That turns out to be somewhat
awkward, especially with SPL, and has resulted in a watchdog callback
not being registered, thus causing the board to prematurely reset.

We already rely on gd->cyclic reliably being set to NULL by the asm
code that clears all of gd. Now that the cyclic list is a hlist, and
thus an empty list is represented by a NULL head pointer, and struct
cyclic_drv has no other members, we can just as well drop a level of
indirection and put the hlist_head directly in struct
global_data. This doesn't increase the size of struct global_data,
gets rid of an early malloc(), and generates slightly smaller code.

But primarily, this avoids having to call cyclic_init() early; the cyclic
infrastructure is simply ready to register callbacks as soon as we
enter C code.

We can still end up with schedule() being called from asm very early,
so we still need to check that gd itself has been properly initialized
[*], but once it has, gd->cyclic_list is perfectly fine to access, and
will just be an empty list.

As for cyclic_uninit(), it was never really the opposite of
cyclic_init() since it didn't free the struct cyclic_drv nor set
gd->cyclic to NULL. Rename it to cyclic_unregister_all() and use that
in test/, and also insert a call at the end of the board_init_f
sequence so that gd->cyclic_list is a fresh empty list before we enter
board_init_r().

A small piece of ugliness is that I had to add a cast in
cyclic_get_list() to silence a "discards 'volatile' qualifier"
warning, but that is completely equivalent to the existing handling of
the uclass_root_s list_head member.

[*] I'm not really sure where we guarantee that the register used for
gd contains 0 until it gets explicitly initialized, but that must be
the case, otherwise testing gd for being NULL would not make much sense.

cyclic: use a flag in gd->flags for recursion protection

2022-11-02T07:41:20+00:00

As a preparation for future patches, use a flag in gd->flags rather
than a separate member in (the singleton) struct cyclic_drv to keep
track of whether we're already inside cyclic_run().
