Subject[PATCH] ARM: dts: stm32f7: add STM32f769I & stm32f746 discovery board support
Message-ID<ttNw5-7aM-3@gated-at.bofh.it>
Stm32f769I & stm32f746 are MCUs of stm32f7 family. Here are the major
spces of the two boards:

stm32f769I discovery board:
	- Cortex-M7 core @216MHz
	- 2MB mcu internal flash
	- 512KB internal sram
	- 16MB sdram memory
	- 64MB qspi flash memory
	- 4 inch wvga LCD-TFT Display

stm32f746 discovery board:
	- Cortex-M7 core @216MHz
	- 1MB mcu internal flash
	- 320KB internal sram
	- 8MB sdram memory
	- 16MB qspi flash memory
	- 4.3 inch 480x272 LCD-TFT display
