[PATCH v4 5/6] ARM: dts: am43x-epos-evm: fix reg and range property of GPMC NAND node

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1) NAND device memory is not directly accessible to CPU, its indirectly accessed
   via registers. So the 'reg' property for GPMC NAND nodes should be limited to
   address range of internal GPMC registers only.
2) Also, minimum granularity of address space under a GPMC chip-select is 16MB
   so 'range' property for GPMC NAND node should specify 16MB as its memory-size
3) On AM437x, address map of external memory accessible via GPMC starts from 0x0
