acpi: Enable ACPI table generation by default on x86

2020-07-17T06:32:24+00:00

This should ideally be used by all x86 boards in U-Boot. Enable it by
default. If some boards don't use it, the cost is small.

dm: Add support for simple-pm-bus

2020-07-01T07:01:21+00:00

This type of bus is used in Linux to designate buses which have power
domains and/or clocks which need to be enabled before their child devices
can be used. Because power domains are automatically enabled before probing
in U-Boot, we just need to enable any clocks present.

dm: core: Add basic ACPI support

2020-04-16T06:36:28+00:00

ACPI (Advanced Configuration and Power Interface) is a standard for
specifying information about a platform. It is a little like device
tree but the bindings are part of the specification and it supports an
interpreted bytecode language.

Driver model does not use ACPI for U-Boot's configuration, but it is
convenient to have it support generation of ACPI tables for passing to
Linux, etc.

As a starting point, add an optional set of ACPI operations to each
device. Initially only a single operation is available, to obtain the
ACPI name for the device. More operations are added later.

Enable ACPI for sandbox to ensure build coverage and so that we can add
tests.

Kconfig: Varios: Fix more SPL, TPL dependencies

2019-08-26T15:46:29+00:00

Several options are presenting themselves on a various boards
where the options are clearly not used.  (ie, SPL/TPL options
when SPL or TPL are not defined)

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.  In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.

This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

dm: core: Change platform specific translation-offset handling

2019-04-24T02:26:43+00:00

Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.

This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the Kconfig

2018-12-10T06:22:30+00:00

It is currently not possible to include the support to remove devices in
the SPL. This is however needed by platforms that re-select their dtb after
DM is initialized; they need to remove all the previously bound devices
before triggering a scan of the new DT.

Add a Kconfig option to be able to include the support for device removal
in the SPL.

dm: replace dm_dbg() with pr_debug()

2017-10-04T16:00:21+00:00

As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

spl: dm: Kconfig: split REGMAP/SYSCON support for TPL from SPL

2017-08-13T15:12:20+00:00

This change introduces TPL variants of the REGMAP and SYSCON config
options (i.e. TPL_REGMAP and TPL_SYSCON in analogy to SPL_REGMAP and
SPL_SYSCON) in preparation of a finer-grained feature selection for
building feature-rich TPL variants.

SPL_REGMAP and SPL_SYSCON were marked as depending on DM, when a
