Per ONFI specification (Rev. 4.0), if the CRC of the first parameter page read is not valid, the host should read redundant parameter page copies until it finds a valid copy. If all three parameter pages have invalid CRC values, the bit-wise majority may be used to recover the contents of the parameter pages from the parameter page copies present.
The FSL NAND driver only reads the first page. The first patch fixes the driver to read all three parameter pages. The second patch is the change for using bit-wise majority to recover the contents of ONFI parameter.
Jane Wan (2): Fix FSL NAND driver to read all ONFI parameter pages Use bit-wise majority to recover the contents of ONFI parameter
