This patch adds 4 BIT ECC support in the DaVinci NAND driver. Tested on both the DM355 and DM365.
Signed-off-by: Sandeep Paulraj s-paulraj@ti.com
When I build with this patch, but without 4 bit enabled, I get this:
davinci_nand.c: In function ‘nand_davinci_4bit_correct_data’: davinci_nand.c:292: warning: unused variable ‘this’ davinci_nand.c: At top level: davinci_nand.c:208: warning: ‘nand_davinci_4bit_enable_hwecc’ defined but not used davinci_nand.c:242: warning: ‘nand_davinci_4bit_calculate_ecc’ defined but not used davinci_nand.c:291: warning: ‘nand_davinci_4bit_correct_data’ defined but not used
We should only build the 4bit code when the board config has asked for it.
