The DMA setup sequence is completely differenct 21 between 32bit / 64bit AXI bus variants. 22 23 If your Denali NAND controller is the 64-bit variant, say Y. 24 Otherwise (32 bit), say N. 25 26config NAND_DENALI_SPARE_AREA_SKIP_BYTES 27 int "Number of bytes skipped in OOB area" 28 depends on NAND_DENALI 29 range 0 63 30 help 31 This option specifies the number of bytes to skip from the beginning 32 of OOB area before last ECC sector data starts. This is potentially 33 used to preserve the bad block marker in the OOB area. 34 35config NAND_VF610_NFC 36 bool "Support for Freescale NFC for VF610/MPC5125" 37 select SYS_NAND_SELF_INIT 38 help 39 Enables support for NAND Flash Controller on some Freescale 40 processors like the VF610, MPC5125, MCF54418 or Kinetis K70. 41 The driver supports a maximum 2k page size.

In absence of this 68 config, bus-width of NAND device is assumed to be either 8-bit and later 69 determined by reading ONFI params. 70 Above config is useful when NAND device's bus-width information cannot 71 be determined from on-chip ONFI params, like in following scenarios: 72 - SPL boot does not support reading of ONFI parameters. This is done to 73 keep SPL code foot-print small. 74 - In current U-Boot flow using nand_init(), driver initialization 75 happens in board_nand_init() which is called before any device probe 76 (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are 77 not available while configuring controller. So a static CONFIG_NAND_xx 78 is needed to know the device's bus-width in advance. 79 80if SPL 81 82config SPL_NAND_DENALI 83 bool "Support Denali NAND controller for SPL" 84 help 85 This is a small implementation of the Denali NAND controller 86 for use on SPL. 87 88config SPL_NAND_SUNXI 89 bool "Support for NAND on Allwinner A20 in SPL" 90 depends on MACH_SUN7I 91 ---help--- 92 Enable support for NAND.
