Detailed Description

struct nand_ecc_ctrl - Control structure for ecc : ecc mode : number of ecc steps per page : data bytes per ecc step : ecc bytes per step : total number of ecc bytes per page : padding information for syndrome based ecc generators : padding information for syndrome based ecc generators : ECC layout control struct pointer : function to control hardware ecc generator. Must only be provided if an hardware ECC is available : function for ecc calculation or readback from ecc hardware : function for ecc correction, matching to ecc generator (sw/hw) : function to read a raw page without ECC : function to write a raw page without ECC : function to read a page according to the ecc generator requirements : function to write a page according to the ecc generator requirements : function to read chip OOB data : function to write chip OOB data
