* Pin SPI_BOOT_FLASH_EN (GPIO 1.9) is a switch for either using the

* ecspi1, but muxed to different pins. The DHCOM SPI1 interface uses
* the pins PAD_LCD_DATA21..23 and the SPI bootflash uses the pins
* PAD_CSI_DATA04..07. If the SPI bootflash is enabled the pins for
* DHCOM GPIOs N/O/P/Q/R/S/T/U aren't usable anymore, because they
* are used for the bus interface to the SPI bootflash. The GPIOs are
* disconnected by a buffer which is also controlled via the pin
* SPI_BOOT_FLASH_EN. Therefore the access to the bootflash is a
* special case and is disabled by setting GPIO 1.9 to high.
