2017.2 Zynq UltraScale+ MPSoC: U-boot 'sf test' command failed for QSPI x4 at 100Mhz

描述

When operating at 100MHZ 4-bit mode in u-boot (sf probe 0 100000000), the test command (sf test 0x2000000 0x80000) fails.

When tested in 4-bit mode with 50HZ QSPI frequency, sf tests are working fine. 1-bit and 2-bit test are also working at 100MHz.

解决方案

To resolve this issue, the attached patches need to be applied.
