Changes in v8:
- Check NAND status in vf610_nfc_write_page

Changes in v7:
- (accidentally none)

Changes in v6:
- Checkpatch style fixes
- Subject change

Changes in v5:
- Fix COMMAND_NADDR_BYTES macro (fixes oob/page test issues)
- Renamed page_access to data_access
- Removed unclear debugging messages
- Introduce vf610_nfc_fill_row to avoid code duplication in
  vf610_nfc_(read|write)_page
- Add patch to enable ONFI SET/GET_FEATURES
- Comment/commit message fixes

Changes in v4:
- Rebased to nand/next
- Simplify filling of address cycles
- Use accessors for SRAM (vf610_nfc_rd_from_sram/vf610_nfc_wr_to_sram)
- Use two op-parser patterns to avoid a single command reading and writing
  in a single operation
- Implement (read|write)_(page|oob)[_raw] to set page_access
- Set and clear vf610_nfc_ecc_mode in ecc (read|write)_page
- Clear/set 16-bit config when 16-bit bus is used and 8-bit access is
  requested

Changes in v3:
- Separate exec_op() callback addition and removal of old callbacks
- Push data into regs in one function
- Readd op parser
- Implement custom read/write page for hardware ECC
- Rely on generic ecc.write_page_raw
- Use nand_read_oob_op instead of nand_read_page_op
