The Denali NAND block loses configuration when put in reset. Specifically, RB_PIN_ENABLED, CHIP_ENABLE_DONT_CARE, SPARE_AREA_SKIP_BYTES and SPARE_AREA_MARKER are lost. Since mainline Linux depends on the configuration programmed into the Denali NAND controller by the bootloader, do not reset the controller before starting the kernel, otherwise the kernel will read bogus values and fail to use the NAND.
