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.

spl: unbreak CONFIG_SPL_MULTI_DTB_FIT after fixing CONFIG_OF_EMBED

2018-02-14T17:14:16+00:00

With commit 9bd76b807636 ("spl: make CONFIG_OF_EMBED pass dts through
fdtgrep"), CONFIG_SPL_MULTI_DTB_FIT has been broken because
cmd_fdtgrep was now unknown in scripts/Makefile.spl after moving
it to dts/Makefile. This bug has been introduced with v2018.01.

This patch moves cmd_fdtgrep from dts/Makefile to scripts/Makefile.lib
and includes scripts/Makefile.lib in scripts/Makefile.spl.

spl: make CONFIG_OF_EMBED pass dts through fdtgrep

2017-11-30T03:36:58+00:00

Building spl with CONFIG_OF_EMBED enabled results in an error message
on my board: "SPL image too big". This is because the fdtgrep build
step is only executed for CONFIG_OF_SEPARATE.

Fix this by moving the fdtgrep build step ('cmd_fdtgreo') from
scripts/Makefile.spl to dts/Makefile so that the reduced dtb is
available for all kinds of spl builds.

The resulting variable name for the embedded device tree blob changes,
too, which is why common.h and fdtdec.c have tiny changes.

Revert "devicetree: use wildcard to clean arch subdir"

This reverts commit 67871a595873930a0a536b1685e5caac53766701.

Since that commit, out-of-tree cleaning emits lots of warnings.

devicetree: use wildcard to clean arch subdir

Use wildcard to clean arch subdirectories, as it is cleaner than
listing all the arch which builds dtb.

fdt: Add DEV_TREE_BIN option to specify a device tree binary file

2014-06-11T20:25:46+00:00

In some cases, an externally-built device tree binary is required to be
attached to U-Boot. An example is when using image signing, since in that
case the .dtb file must include the public keys.

Add a DEV_TREE_BIN option to the Makefile, and update the documentation.

Usage is something like:

	make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb

kbuild: use cmd_shipped instead of cmd_copy

We already have cmd_shipped in scripts/Makefile.lib.
Use it rather than defining a new command cmd_copy.
