18 | help | |
19 | The Denali NAND controller IP has some variations in terms of | |
20 | the bus interface. 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. | |

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. | |

85 | config SYS_NAND_BUSWIDTH_16BIT | |
86 | bool "Use 16-bit NAND interface" | |
87 | depends on NAND_VF610_NFC | |
88 | help | |
89 | Indicates that NAND device has 16-bit wide data-bus. In absence of this | |
90 | config, bus-width of NAND device is assumed to be either 8-bit and later | |
91 | determined by reading ONFI params. | |
92 | Above config is useful when NAND device's bus-width information cannot | |
93 | be determined from on-chip ONFI params, like in following scenarios: | |
94 | - SPL boot does not support reading of ONFI parameters. This is done to | |
95 | keep SPL code foot-print small. | |
96 | - In current U-Boot flow using nand_init(), driver initialization | |
97 | happens in board_nand_init() which is called before any device probe | |
98 | (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are | |
99 | not available while configuring controller. So a static CONFIG_NAND_xx | |
100 | is needed to know the device's bus-width in advance. | |
