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>
2015-01-12common/board_f.c: fix compile error when tracing disabledKevin Hilman
When CONFIG_TRACE is disabled, linking fails with: common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init' To fix, wrap trace init calls with #ifdef CONFIG_TRACE. While at it, remove the static inline version of the init call from trace.h as suggested by Simon Glass, since it doesnt work.

2013-06-26Add trace librarySimon Glass
Add a library which supports tracing of execution using built-in gcc features and a microsecond timer. This can be used to record a list of function which are executed, along with a timestamp for each. Later this information can be sent to the host for processing.
