From a492fdffa3c86f6b8420b6433a2ce07271597324 Mon Sep 17 00:00:00 2001 From: Luis Araneda Date: Fri, 27 Jul 2018 04:43:42 -0400 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).
