[U-Boot] [PATCH] ram: stm32_sdram: Adds stm32f746-disco fix for HardFault at booting

[Patrice CHOTARD]

Hi again Mark ;-)

I dig into this issue and i think a better fix must be done directly 
into the board/st/stm32f746-disco/stm32f746-disco.c.

At the same occasion, some cleaning can be done using last fdtdec_xxx() API.

I will submit a patch for that which fix the issue you saw.

Thanks

Patrice
