2019-04-26mtd: nand: raw: Fix CONFIG_SYS_NAND_DRIVER_ECC_LAYOUT behaviorGregory CLEMENT
The purpose of "mtd: nand: raw: allow to disable unneeded ECC layouts" was to allow disabling the default ECC layouts if a driver is known to provide its own ECC layout. However, this commit did the opposite and disabled the default layout when it was _not_ selected. It breaks all the NAND drivers not providing their own ECC layout this patch fix this situation. It was tested with the lpc32xx_nand_slc driver.

2019-04-22mtd: nand: provide several helpers to do common NAND operationsBoris Brezillon
Linux commit 97d90da8a88 ("mtd: nand: provide several helpers to do common NAND operations") This is part of the process of removing direct calls to ->cmdfunc() outside of the core in order to introduce a better interface to execute NAND operations. Here we provide several helpers and make use of them to remove all direct calls to ->cmdfunc(). This way, we can easily modify those helpers to make use of the new ->exec_op() interface when available.

Each ECC layout consumes about 2984 bytes in the .data section. Allow to disable the default ECC layouts if a driver is known to provide its own ECC layout.

2018-09-20mtd: move NAND files into a raw/ subdirectoryMiquel Raynal
NAND flavors, like serial and parallel, have a lot in common and would benefit to share code. Let's move raw (parallel) NAND specific code in a raw/ subdirectory, to ease the addition of a core file in nand/ and the introduction of a spi/ subdirectory specific to SPI NANDs.
