[U-Boot] [PATCH v4 09/27] mtd: move NAND files into a raw/ subdirectory

Miquel Raynal
2018-07-13T12:31:55Z

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.

- Above config is useful when NAND device's bus-width information cannot
- be determined from on-chip ONFI params, like in following scenarios:
- - SPL boot does not support reading of ONFI parameters. This is done to
- keep SPL code foot-print small.
- - In current U-Boot flow using nand_init(), driver initialization
- happens in board_nand_init() which is called before any device probe
- (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
- not available while configuring controller. So a static CONFIG_NAND_xx
