The generated .S files for fonts and splash screens use .incbin with the full prerequisite path. When building with O= this bakes an absolute path into the .S file. If the build directory is later used on a different machine (e.g. in a container), the assembler cannot find the source file. Follow the existing DTB convention: rename the object targets to use compound suffixes (.ttf.o, .bmp.o), switch the pattern rules from direct $(call cmd,...) to FORCE + $(call if_changed,...), and register the new suffixes with intermediate_targets so that kbuild loads their .cmd files. This lets if_changed detect when the recorded command (including source paths) has changed and regenerate the .S file automatically. The EFI rule is left unchanged since its prerequisite is a generated file in the build directory, like the DTB and DTBO rules. The intermediate_targets entries stay in scripts/Makefile.build rather than moving to scripts/Makefile.lib-u-boot, because that file is included before intermediate_targets is defined and 'targets' is ':=', so a '$(call intermediate_targets, ...)' inside it would expand to empty and silently drop the entries. To keep the upstream block untouched, the U-Boot additions go in a separate 'targets +=' block immediately below.

The Kconfig menu "TrueType Fonts" should only be shown if TrueType is enabled. Put all TrueType dependent customization within one if statement. Remove `depends TRUETYPE` clauses.

A TrueType font for U-Boot should fulfill the following requirements: * mono spaced * support full code page 437 * easily readable Unfortunately none of the fonts provided with U-Boot fulfills all of these requirements. Let's add the DejaVu Mono font. To reduce the code size the characters are limited to code page 437.

At present it is possible to enable TrueType support but not include any fonts. This results in a blank display. Select Nimbus as the default font to avoid this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
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. Signed-off-by: Tom Rini <trini@konsulko.com>
