    ARM: dts: am43xx: add support for parallel NAND flash · f68e355c
    Pekon Gupta 提交于
    This patch:
     - enables GPMC h/w and ELM h/w engine for AM43xx devices (am4372.dtsi)
     - adds pinmux and DT node for Micron 4K-paged x8 NAND device (MT29F4G08AB)
       present on following boards:
    
       am43x-epos-evm:
    	On this board, NAND Flash control lines are muxed with QSPI, Thus only
            one of the two can be used at a time. Selection is controlled by:
            (a) dynamically driving following GPIO pin from software
                GPMC_A0(GPIO) == 0 NAND is selected (default)
                GPMC_A0(GPIO) == 1 eMMC is selected
