[u-boot][PATCH v2 0/4] Introduce MEMORY uclass and TI GPMC driver

[Roger Quadros]

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.

  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
