During the last months, Boris Brezillon shared his work to support
serial flashes within Linux. First, he delivered (and merged) a new
layer called spi-mem. He also initiated in Linux MTD subsystem the move
of all 'raw' NAND related code to a raw/ subdirectory, adding at the
same time a NAND core that would be shared with all NAND devices. Then,
he contributed a generic SPI-NAND driver, making use of this NAND core,
as well as some vendor code to drive a few chips.
On top of this work, I added an 'mtd' U-Boot command to handle all sort
of MTD devices. This should become the default command instead of having
one per flash flavor ('sf', 'nand', 'spi-nand' ?).
The series has been tested on an Ocelot board PCB123 (VSC7514),
featuring a Macronix SPI NAND chip.
TL;DR: the series contains:
- Various fixes and re-organization of the MTD subsystem.
- The introduction of the SPI-mem interface.
- The addition of the generic SPI-NAND driver (and its bindings).
- Several SPI NAND chip drivers (Macronix, Micron, Winbond).
- A new 'mtd' command.
- DT changes to make use of a SPI NAND on the Ocelot board.
Any comments on the code, the organization and the respect of U-Boot
driver model will be welcome.
Thanks,
