From: Christophe Kerello <christophe.kerello@xxxxxx>
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
