Implement read of OOB area only. When using column and sector size properties, only parts of the page can be read. However, this works only when hardware ECC is disabled, otherwise the ECC engine would ruin the data in the buffer. To allow OOB only reads, three points had to be addressed: - Set ECC mode per command. - Handle NAND_CMD_READOOB seperate. Make sure column and sector size is correctly set up, while disabling ECC. - Now, the OOB data end up at the beginning of the buffer. Remove the special handling of OOB (spareonly). Especially bad block scans benefit from this change. On a 512MiB SLC NAND device, the bad block scan took 1.5s less than before. Signed-off-by: Stefan Agner <stefan@agner.ch> |
