[U-Boot] [PATCH] arm: zynq: dts: add spi flash node to zedboard
Add a flash node to fix the detection of the memory IC. With the changes introduced with commit 8fee8845e754 ("enf_sf: reuse setup_flash_device instead of open coding it") the SPI speed is now read from device-tree or a default value is applied. This replaced the old behavior of setting the SPI speed to CONFIG_ENV_SPI_MAX_HZ.
As this board didn't have a flash node, the default value was applied to the SPI speed, producing an error when probing the flash memory (speed too slow).
