Subject: [PATCH] ARM: dts: stm32f7: add stm32f769I & stm32f746 discovery board support
Stm32f769I & stm32f746 are MCUs of stm32f7 family. Here are the major
specs 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
