[PATCH v4 1/2] arm64: dts: ti: k3-am64-main: Add GPMC memory controller node

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

 



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
