Hi,
This series introduces the MEMORY controller uclass for the drivers that exist in drivers/memory directory.
With that, we add the TI GPMC Memory controller driver as the first user of this uclass.
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
The driver is pulled straight from the Linux kernel and adapted for u-boot.
This driver will take care of setting up the GPMC based on the settings specified in the Device tree and then probe its children.
cheers, -roger
Changelog: v3: - Use CONFIG_MEMORY instead of CONFIG_DM_MEMORY - Introduce CONFIG_SPL_MEMORY and use it to gate inclusion of of drivers/memory for SPL build - Make TI_GPMC depend on OF_CONTROL and CLK as well
v2: - Introduce MEMORY uclass
Roger Quadros (4): dm: memory: Introduce new uclass scripts: Makefile.spl: Enable memory drivers to be built for SPL dt/bindings: memory: Add bindings for TI GPMC driver memory: Add TI GPMC driver
