- Subject: [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).
