14eb61aa25 mtd: nand: raw: rockchip_nfc: add flash_node to chip structure
Add flash_node to the rockchip_nfc driver chip structure in order
to find the partitions in the add_mtd_partitions_of() function.

1b3fcb3c04 mtd: nand: raw: rockchip_nfc: add layout structure
The MTD framework in U-boot is not identical for drivers ported
from Linux. The rockchip_nfc driver was ported with OOB ops functions
while the framework expects a layout structure per chip.
Fix by adding a structure with OOB data and remove unused functions.

4473b87b28 mtd: nand: raw: rockchip_nfc: remove the compatible string "rockchip,rk3308-nfc"
The compatible string for rk3308 has as fallback string
"rockchip,rv1108-nfc". As there is no logic in probe priority between
the SoC orientated string and the fall back, so remove the compatible
string "rockchip,rk3308-nfc" from the driver.

40a1351080 mtd: nand: raw: rockchip_nfc: use dev_read_addr_ptr
The fdt_addr_t and phys_addr_t size have been decoupled.
A 32bit CPU can expext 64-bit data from the device tree parser,
so use dev_read_addr_ptr in the rockchip_nfc.c file.

1cefed1e39 nand.h: Cleanup linux/mtd/rawnand.h usage
We only include <linux/mtd/rawnand.h> in <nand.h> for the forward
declaration of struct nand_chip, so do that directly.  Then, include
<linux/mtd/rawnand.h> where required directly.

b12dc5d6fa mtd: nand: NFC drivers for RK3308, RK2928 and others
This driver supports Rockchip NFC (NAND Flash Controller) found on
RK3308, RK2928, RKPX30, RV1108 and other SOCs. The driver has been
tested using 8-bit NAND interface on the ARM based RK3308 platform.

Support Rockchip SoCs and NFC versions:
- PX30 and RK3326(NFCv900).
	ECC: 16/40/60/70 bits/1KB.
	CLOCK: ahb and nfc.
- RK3308 and RV1108(NFCv800).
	ECC: 16 bits/1KB.
	CLOCK: ahb and nfc.
- RK3036 and RK3128(NFCv622).
	ECC: 16/24/40/60 bits/1KB.
	CLOCK: ahb and nfc.
- RK3066, RK3188 and RK2928(NFCv600).
	ECC: 16/24/40/60 bits/1KB.
	CLOCK: ahb.

Supported features:
- Read full page data by DMA.
- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)

Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to
  use  the BBT(bad block table).
