- rawnand: omap_gpmc: driver model support
Enables SPL NAND support for ARCH_K3 by enabling
SPL_NAND_INIT and SPL_SYS_NAND_SELF_INIT.
Legacy OMAP2plus platforms still rely on SPL_NAND_AM33XX_BCH
instead.

This implementation is ported from the rework done by Boris Brezillon
in Linux. This porting is done based on linux-5.4-at91. The driver is
tested in sam9x60ek, sama5d3_xplained, sam9x75eb and sama7g54-ddr3-eb.
Changes done includes
- Adapt GPIO descriptor apis for U-Boot. Use gpio_request_by_name_nodev,
dm_gpio_get_value etc.
- Use U_BOOT_DRIVER instead of platform_driver.
- Replace struct platform_device with struct udevice
- Check the status of nfc exec operation by polling the status
register instead of interrupt based handling
- DMA operations not supported. Remove it
- Adapt DT parsing to U-Boot APIs

This patch adds NAND flash controller driver for MediaTek MT7621 SoC.
The NAND flash controller of MT7621 supports only SLC NAND flashes.
It supports 4~12 bits correction with maximum 4KB page size.

Add a driver for Macronix raw NAND controller.
This patch referred from linux mxic_nand.c. The difference from the
linux version is described here.
1. In order to adapt to the uboot nand framework, add function
binding (cmdfunc, read_byte, read_buf, write_buf).
2. Added parsing command format to use hardware correctly.
3. Remove the incompatible functions of Uboot.

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).

The driver adds the support for the STMicroelectronics FMC2 NAND
Controller found on STM32MP SOCs.
This patch adds the polling mode, a basic mode that do not need
any DMA channels.
Only NAND_ECC_HW mode is actually supported.
The driver supports a maximum 8k page size.
The following ECC strength and step size are currently supported:
- nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8)
- nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4)
- nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ECC
based on Hamming)
This patch has been tested on Micron MT29F8G08ABACAH4.

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.
