[PATCH v2 1/3] mtd: introduce the mtd_pairing_scheme concept

2016-06-20 Thread Boris Brezillon
MLC and TLC NAND devices are using NAND cells exposing more than one bit, but instead of attaching all the bits in a given cell to a single NAND page, each bit is usually attached to a different page. This concept is called 'page pairing', and has significant impacts on the flash storage usage. The
