+- 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).
