Status: For testing only! Version: V1 Title: Enable RK3066 NANDC for MK808. The majority of Rockchip devices use a closed source FTL driver to reduce wear leveling. This patch serie proposes an experimental raw NAND controller driver for basic tasks in order to get the bindings and the nodes accepted for in the dts files. What does it do: On module load this driver will reserve its resources. After initialization the MTD framework will then try to detect the type and number of NAND chips. When all conditions are met, it registers it self as MTD device. This driver is then ready to receive user commands such as to read and write NAND pages. Test examples: # dd if-/dev/mtd0 of=dd.bin bs=8192 count=4 # nanddump -a -l 32768 -f nanddump.bin /dev/mtd0 Not tested: NANDC version 9. NAND raw write. RK3066 still has no support for Uboot. Any write command would interfere with data structures made by the boot loader. Etc. Problems: No bad block support. Most devices use a FTL bad block map with tags that must be located on specific page locations which is outside the scope of the raw MTD framework. No partition support. A FTL driver will store at random locations and a linear user specific layout does not fit within the generic character of this basic driver. Etc.
