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>
2018-03-13board: stm32: switch to DM STM32 timerPatrice Chotard
Use available DM stm32_timer driver instead of dedicated mach-stm32/stm32fx/timer.c. Remove all defines or files previously used for timer usage in arch/arm/include/asm/arch-stm32fx and in arch/arm/mach-stm32/stm32fx Enable DM STM32_TIMER for STM32F4/F7 and H7.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.
