The GPMC is a unified memory controller dedicated for interfacing with external memory devices like - Asynchronous SRAM-like memories and ASICs - Asynchronous, synchronous, and page mode burst NOR flash - NAND flash - Pseudo-SRAM devices Signed-off-by: Roger Quadros <rogerq@kernel.org> --- arch/arm64/boot/dts/ti/k3-am64-main.dtsi | 19 +++++++++++++++++++ arch/arm64/boot/dts/ti/k3-am642-evm.dts | 4 ++++ arch/arm64/boot/dts/ti/k3-am642-sk.dts | 4 ++++ 3 files changed, 27 insertions(+)
