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.
