As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

On Rockchip SoCs the first boot stages are written on NAND
with help of manufacturer software that uses a different format
then the MTD framework. Skip the automatic BBT scan with the
NAND_SKIP_BBTSCAN option to be able to pass the driver probe
function and to let the original data unchanged.

Rockchip boot blocks are written per 4 x 512 byte sectors per page.
Each page must have a page address (PA) pointer in OOB to the next page.
Pages are written in a pattern depending on the NAND chip ID.
This logic used to build a page pattern table is not fully disclosed and
is not easy to fit in the MTD framework.
The formula in rk_nfc_write_page_hwecc() function is not correct.
Make hwecc and raw behavior identical.
Generate boot block page address and pattern for hwecc in user space
and copy PA data to/from the already reserved last 4 bytes before EEC
in the chip->oob_poi data layout.

The MTD framework reserves 1 or 2 bytes for the bad block marker
depending on the bus size. The rockchip_nfc driver currently only
supports a 8 bit bus, but reserves standard 2 bytes for the BBM.
The first free OOB byte is therefore OOB2 at offset 2.
Page address(PA) bytes are moved to the last 4 positions before
ECC. Update the description for U-boot.

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.

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.

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.

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).
