    RT #90499: STM32F4X9-SOM NOR/SDRAM errata 2.8.7 fix · 427d84f4
    Pavel Boldin authored
    Copy image from NOR to SDRAM through On-Chip RAM buffer
    setting SDRAM to Self-Refresh on each copy.
    
    Implement flash_read16, flash_write16 and flash_write_buffer
    to disable/enable SDRAM on flash access.
    
    Start and immediately put SDRAM in self-refresh on start-up for flash
    to work correctly.
