    Title: Memories

    About: Purpose
        Methods for initializing memories (SDRAM, etc.) and remapping.

    About: Usage
        1 - Remap the Flash at address 0 using <BOARD_RemapFlash>.
        2 - Remap the internal RAM at address 0 using <BOARD_RemapRam>.
        3 - Initialize an external SDRAM using <BOARD_InitializeSdram>.
