Brian Norris e99d8b089a mtd: add MEMWRITE ioctl ... Implement a new ioctl for writing both page data and OOB to flash at the same time. This ioctl is intended to be a generic interface that can replace other ioctls (MEMWRITEOOB and MEMWRITEOOB64) and cover the functionality of several other old ones, e.g., MEMWRITE can: * write autoplaced OOB instead of using ECCGETLAYOUT (deprecated) and working around the reserved areas * write raw (no ECC) OOB instead of using MTDFILEMODE to set the per-file-descriptor MTD_FILE_MODE_RAW * write raw (no ECC) data instead of using MTDFILEMODE (MTD_FILE_MODE_RAW) and using standard character device "write" This ioctl is especially useful for MLC NAND, which cannot be written twice (i.e., we cannot successfully write the page data and OOB in two separate operations). Instead, MEMWRITE can write both in a single operation. Note that this ioctl is not affected by the MTD file mode (i.e., MTD_FILE_MODE_RAW vs. MTD_FILE_MODE_NORMAL), since it receives its write mode as an input parameter.
