Subject: [PATCH v2 0/3] mtd: rawnand: add STM32 FMC2 NAND flash controller driver

From: Christophe Kerello <christophe.kerello@...com>

This patchset adds the support for the STMicroelectronics FMC2 NAND flash
controller found on STM32MP SOCs.

This patchset supports:
  - the command sequencer feature, a hardware accelerator for read/write
    within a page
  - the manual mode feature, useful for debug purpose
  - a maximum 8k page size
  - following ECC strength and step size
	- 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 patchset has been tested on Micron MT29F8G08ABACAH4 (8-bit SLC NAND)
and MT29F8G16ABACAH4 (16-bit SLC NAND)

Changes v2:
 - separate the controller structure and the NAND chip structure
 - remove timings description from the device tree
 - fix typo issues
 - fix kbuildrobot issues
