nand_ecclayout is present in mtd.h at Linux. Move this structure to mtd.h to comply with Linux.
Also, increase the ecc placement locations to 640 to suport device having writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640.
Signed-off-by: Prabhakar Kushwaha prabhakar@freescale.com CC: Vipin Kumar vipin.kumar@st.com --- Changes for v2: Incorporated Scott's comments - move nand_ecclayout to mtd.h - updated OOBFREE, ECCPOS max entries
Changes for v3: Sending as it is Changes for v4: Sending as it is Changes for v5: Sending as it is
