The Macronix MX35LF1G24AD(/2G24AD/4G24AD) are 3V, 1G/2G/4Gbit serial
SLC NAND flash device (without on-die ECC).

Validated by read, erase, read back, write, read back on Xilinx Zynq
PicoZed FPGA board which included Macronix SPI Host(drivers/spi/spi-mxic.c)
& S/W BCH ecc(drivers/mtd/nand/ecc-sw-bch.c) with bug fixing patch
(mtd: nand: ecc-bch: Fix the size of calc_buf/code_buf of the BCH).
