mtd: rawnand: stm32_fmc2: add STM32 FMC2 NAND flash controller driver
The driver adds the support for the STMicroelectronics FMC2 NAND
Controller found on STM32MP SOCs.
This patch is based on FMC2 command sequencer.
The purpose of the command sequencer is to facilitate the programming
and the reading of NAND flash pages with the ECC and to free the CPU
of sequencing tasks.
It requires one DMA channel for write and two DMA channels for read
operations.
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 and
MT29F8G16ABACAH4
