83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

20fe38e75a clk: clk_stm32f: Move SYSCFG clock setup into configure_clocks()
Move SYSCFG clock setup into configure_clocks() instead of calling
clock_setup() from board file.

As this clock is only needed in case of ethernet enabled and as
both stm32f4 and stm32f7 are using the Designware ethernet IP,
we use CONFIG_ETH_DESIGNWARE to only enable this clock if needed.

Move the RMII setup from board_early_init_f() to board_init()
to insure that RMII bit is set only when clock driver is initialized.

1a73bd842e spl: stm32f7: configure for xip booting
With xip booting configuration, we don't need to copy the next image
(U-Boot or linux xipimage) from flash to sdram area.

Flash memory organization is like this:
	spl-U-Boot:	u-boot-spl.bin 	: 0x0800_0000
	U-Boot :	u-boot-dtb.bin	: 0x0800_8000
	linux :		xipImage	: 0x0800_8000

It is also possible to have U-Boot binary & linux binaries configured at
different addresses of flash memory like U-Boot at 0x0800_8000 & linux
xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for
U-Boot as next binary with SPL_OS_BOOT option disabled.
By default, spl is configured to boot linux xipImage.

b97476965b stm32: stm32f7: add spl build support
This commit supports booting from stm32 internal nor flash. spl U-Boot
initializes the sdram memory, copies next image (e.g. standard U-Boot)
to sdram & then jumps to entry point.

Here are the flash memory addresses for U-Boot-spl & standard U-Boot:
	- spl U-Boot		: 0x0800_0000
	- standard U-Boot	: 0x0800_8000

To compile u-boot without spl: Remove SUPPORT_SPL configuration
(arch/arm/mach-stm32/Kconfig)

4b2fd720a7 stm32: Change USART port to USART6 for stm32f746 discovery board
This change is to remove a halt at about 200KiB
while sending a large(1MiB) binary to a micro controller using USART1.
USART1 is connected to a PC via an on-board ST-Link debugger
that also functions as a USB-Serial converter.
However, it seems to loss some data occasionally.
So I changed the serial port to USART6 and connected it to the PC using
an FTDI USB-Serial cable, therefore the transmission was successfully
completed.
