      mtd: nand: Rename nand.h into rawnand.h

      We are planning to share more code between different NAND based
      devices (SPI NAND, OneNAND and raw NANDs), but before doing that
      we need to move the existing include/linux/mtd/nand.h file into
      include/linux/mtd/rawnand.h so we can later create a nand.h header
      containing all common structure and function prototypes.

6d3fa0dfdd mtd: nand: zynq: Add support for the NAND lock/unlock operation
Zynq NAND driver is not support for NAND lock or unlock operation.
Hence, accidentally write into the critical NAND region might cause
data corruption to occur.

This commit is to add NAND lock/unlock command into NAND SMC register
set for NAND lock/unlock operaion.

310995d9f9 mtd: zynq: nand: Move board_nand_init() function to board.c
Putting board_nand_init() function inside NAND driver was not appropriate
due to it doesn't allow board vendor to customise their NAND
initialization code such as adding NAND lock/unlock code.

This commit was to move the board_nand_init() function from NAND driver
to board.c file. This allow customization of board_nand_init() function.

8000d6ea3f mtd: nand: zynq: Add a config option to use 1st stage bootloader timing
In legacy method, 1st stage bootloader was used to configure the HW
setting such as NAND timing. Hence, adding a config option in Zynq
NAND driver for the compatibility of device that using 1st stage
bootloder instead of U-boot SPL.

This commit is to add config option
CONFIG_NAND_ZYNQ_USE_BOOTLOADER1_TIMINGS that allow NAND driver use
timing values set by the 1st stage bootloader, instead of the hard-coded
values in the Zynq NAND driver.

88b81bf792 mtd: nand: drv: use get_nand_dev_by_index()
As part of preparation for nand DM conversion the new API has been
introduced to remove direct access to nand_info array. So, use it here
instead of accessing to nand_info array directly
