And fix a bug of BCH, the size of calc_buf/code_buf is limited to 64 bytes. If someone uses Flash with pagesize: 4096 (for example: MX35LF4G24AD, eccbyte: 104 bytes), some errors will occur during the read operation. So we correct the size of calc_buf/code_buf to mtd->oobsize. This series has been tested on Xilinx Zynq PicoZed FPGA board. Thanks for your time.
