Since 'commit af2f44267 ("fdc spl: use different BOARD_INIT MACRO for spl and tpl")'
board stm32f746-disco can't boot.The macro CONFIG_IS_ENABLED() can't evaluate the value of
CONFIG_SPL_BOARD_INIT as it was defined in include/configs/stm32f746-disco.h
without attributed value.Moving CONFIG_SPL_BOARD_INIT from stm32f746-disco.h to mach-stm32/Kconfig
fixes this issue.Fixes: af2f44267 ("fdc spl: use different BOARD_INIT MACRO for spl and tpl")

Use available DM clk_stm32f.c driver instead of dedicated
mach-stm32/stm32f4/clock.c.Migrate periph_clock defines from stm32_periph.h directly in
CLK driver. These periph_clock defines will be removed when STMMAC,
TIMER2 and SYSCFG drivers will support DM CLK.Enable also CLK flag.

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_8000It 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.Signed-off-by: Vikas Manocha

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_8000To compile u-boot without spl: Remove SUPPORT_SPL configuration

Here is the regions info:- Region0 : 4GB : cacheable & executable.
- Region1 : 512MB : text area : strogly ordered & executable.
- Region2 : 512MB : peripherals : device memory & non-executable.
- Region3 : 512MB : peripherals : device memory & non-executable.
- Region4 : 512MB : cortexM area: strongly ordered & non-executable.Higher region number overrides the lower region configuration.

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.Signed-off-by: Toshifumi NISHINAGA
