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>
2018-03-13arch-stm32: Factorize stm32.h for STM32F4 and F7Patrice Chotard
For STM32F4 and F7 SoCx family, a specific stm32.h file exists. Some common defines are duplicated or even unused in each of these stm32.h. Factorize all common definition in arch/arm/include/asm/stm32f.h and keep specific definitions in each arch/arm/include/asm/arch-stm32fx/stm32.h.

2017-07-10mtd: stm32: use parameter instead of default valuePatrice Chotard
To set wait state, a hard coded value is used instead of using latency parameter. stm32_flash_latency_cfg() is currently used in arch/arm/mach-stm32/stm32f4/clock.c and in drivers/clk/clk_stm32f7.c with, in both case, "5" as parameter. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2016-04-11stm32: stm32_flash: add memory barrier during flash writeVikas Manocha
After writing data to flash space, next instruction is checking if flash controller is busy writing to the flash memory. Memory barrier is required here to avoid transaction re-ordering for data write and busy status check. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
2016-03-26stm32: stm32f4: move flash driver to mtd driver locationVikas Manocha
Same flash driver can be used by other stm32 families like stm32f7. Better place for this driver would be mtd driver location. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
