Subject: [u-boot][PATCH v3 0/4] Introduce MEMORY uclass and TI GPMC driver
Date: Thu, 20 Oct 2022 16:30:45 +0300 [thread overview]
Message-ID: <20221020133049.8398-1-rogerq@kernel.org> (raw)
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
