SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dm: core: Add a comment about the device_remove() flags

2017-08-17T07:44:16+00:00

We should explain which flags are used for this function. Update the
comment to indicate this.

dm: core: Allow binding a device from a live tree

2017-06-01T13:03:08+00:00

When a live tree is being used we need to record the node that was used to
create the device. Update device_bind_with_driver_data() to support this.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

dm: allow setting driver_data before/during bind

2016-05-27T02:48:31+00:00

This will allow a driver's bind function to use the driver data. One
example is the Tegra186 GPIO driver, which instantiates child devices
for each of its GPIO ports, yet supports two different HW instances each
with a different set of ports, and identified by the udevice_id .data
field.

dm: Remove device_probe_child()

2016-01-29T04:01:23+00:00

This function is not used as the use case for it did not eventuate. Remove
it to avoid confusion.

dm: core: allow device_bind() to not return a device pointer

2015-08-31T13:57:29+00:00

This is useful when we want to bind a device, but do not need the

dm: drop CONFIG_DM_DEVICE_REMOVE from uncmd list

2015-08-18T17:46:04+00:00

We do not want to compile the DM remove code for SPL.  Currently,
we undef it in include/config_uncmd_spl.h (for C files) and in
scripts/Makefile.uncmd_spl (for Makefiles).  This is really ugly.

This commit demonstrates how we can deprecate those two files.

Use $(SPL_) for the entry in the Makfile and CONFIG_IS_ENABLED()
in C files.

devres: make Devres optional with CONFIG_DEVRES

2015-08-06T13:44:29+00:00

Currently, Devres requires additional 16 byte for each allocation,
which is not so insignificant in some cases.

Add CONFIG_DEVRES to make this framework optional.
If the option is disabled, devres functions fall back to
non-managed variants.  For example, devres_alloc() to kzalloc(),
devm_kmalloc() to kmalloc(), etc.

Because devres_head is also surrounded by an ifdef conditional,
there is no memory overhead when CONFIG_DEVRES is disabled.
