dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: serial: Handle "stdout-path" with ":options" correctly

2019-12-02T23:18:05+00:00

With commit f0921f5098d8 ("fdt: Sync up to the latest libfdt"),
SiFive Unleashed board does not boot any more. This was due to
the U-Boot local changes commit 77d7fff8cec2 ("fdt: Fix handling
of paths with options in them") to libfdt/fdt_ro.c was dropped
during the libfdt upgrade.

>From the history [1] it was mentioned that the U-Boot changes
commit 77d7fff8cec2 ("fdt: Fix handling of paths with options in
them") was rejected by libfdt upstream, hence we need find another
way to fix the things.

This commit uses another method, by updating serial_check_stdout()
directly to handle the situation of "stdout-path" with ":options".
A simpler way is to change the logic in fdtdec_get_chosen_node()
to do similar thing, but I feel that not every property in chosen
node may have the option in them, hence it would make more sense
to do the special handling in serial_check_stdout() directly.

env: Rename environment.h to env_internal.h

2019-08-11T23:27:31+00:00

This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.

Rename this file and add a comment at the top to indicate its internal
nature.

dm: serial: Introduce ->getinfo() callback

New callback will give a necessary information to fill up ACPI SPCR table,
for example. Maybe used later for other purposes.

dm: serial: Add ->getconfig() callback

2018-12-05T13:06:44+00:00

In some cases it would be good to know the settings, such as parity,
of current serial console. One example might be an ACPI SPCR table
to generate using these parameters.

dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()

2018-11-14T17:16:27+00:00

Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.
