[PATCH 0/5] ADD STM32F746 MCU and STM32746G-Eval board supports

This series adds basic support for STM32F746 MCU and stm32746g-eval board.
With it, you can boot stm32746g-eval board successfully.
In this series timer, usart/uart, exti, rng, basic rcc IPs are supported.
Other Ips (Ethernet, dma, ...) will come later.

For your information:

The STMicrolectornics's STM32F746 MCU has the following main features:
 - Cortex-M7 core running up to @216MHz
 - 1MB internal flash, 320KBytes internal RAM (+4KB of backup SRAM)
 - FMC controller to connect SDRAM, NOR and NAND memories
 - Dual mode QSPI
 - SD/MMC/SDIO support
 - Ethernet controller
 - USB OTFG FS & HS controllers
 - I2C, SPI, CAN busses support
 - Several 16 & 32 bits general purpose timers
 - Serial Audio interface
 - LCD controller
 - HDMI-CEC
 - SPDIFRX 

Regards

Alex
