This is a driver for NAND controller of Intel Moorestown platform.
|
|
|
|
This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
|
|
It includes three layer:
|
|
block layer interface - file ffsport.c
|
|
Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
|
|
Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
|
|
|
|
This driver can be build as modules or build-in.
|
|
|
|
Dependency:
|
|
This driver has dependency on IA Firmware of Intel Moorestown platform.
|
|
It need the IA Firmware to create the block table for the first time.
|
|
And to validate this driver code without IA Firmware, you can change the
|
|
macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
|
|
driver will erase the whole nand flash and create a new block table.

TODO:
|
|
- Enable Command DMA feature support
|
|
- lower the memory footprint
|
|
- Remove most of the unnecessary global variables
|
|
- Change all the upcase variable / functions name to lowercase
|
|
- Some other misc bugs
