2025-04-11Kbuild: Always use $(PHASE_)Tom Rini
It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini <trini@konsulko.com>
2024-10-11global: Rename SPL_ to XPL_Simon Glass
Use XPL_ as the symbol to indicate an SPL build. This means that SPL_ is no-longer set. Signed-off-by: Simon Glass <sjg@chromium.org>
2024-07-30led: Implement software led blinkingMichael Polyntsov
If hardware (or driver) doesn't support leds blinking, it's now possible to use software implementation of blinking instead. This relies on cyclic functions.

2023-12-13led: add TI LP5562 LED driverDoug Zobel
Driver for the TI LP5562 4 channel LED controller. Supports independent on/off control of all 4 channels. Supports LED_BLINK on 3 independent channels: blue/green/red. The white channel can blink, but shares the blue channel blink rate. Heavily based on patch originally from Doug Zobel [1]. I have modified it so it matches the DT bindings in the linux tree, and also follows the linux driver implementation more closely. This should address Tom's concerns, and also matches my goal of making the U-Boot driver work with our existing .dts which is known to work in linux. As our boards only have the R,G,B outputs connected, I have not actually tested how the white channel behaves, but the R,G,B work exactly as expected.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
