+- Parallel Flash support:
+ CONFIG_SYS_NO_FLASH
+
+ Traditionally U-boot was run on systems with parallel NOR
+ flash. This option is used to disable support for parallel NOR
+ flash. This option should be defined if the board does not have
+ parallel flash.
+
+ If this option is not defined one of the generic flash drivers
+ (e.g. CONFIG_FLASH_CFI_DRIVER or CONFIG_ST_SMI) must be
+ selected or the board must provide an implementation of the
+ flash API (see include/flash.h).
+
- DataFlash Support:
CONFIG_HAS_DATAFLASH
Define this option to include a destructive SPI flash
test ('sf test').
- CONFIG_SPI_FLASH_BAR Ban/Extended Addr Reg
-
- Define this option to use the Bank addr/Extended addr
- support on SPI flashes which has size > 16Mbytes.
-
CONFIG_SF_DUAL_FLASH Dual flash memories
Define this option to use dual flash support where two flash
memories can be connected with a given cs line.
Currently Xilinx Zynq qspi supports these type of connections.
+ CONFIG_SPI_FLASH_DATAFLASH SPI based Dataflash
+
+ Define this option to access AT45xxx Dataflash chips support
+ using spi flash interface.

+ If CONFIG_REGEX is defined, the variable_name above is evaluated as a
