2013.4 Linux: Data mismatch in single QSPI flash device at lower frequencies when jffs2 file system is used.

Description

With the latest driver and single QSPI configuration, jffs2 operations will work at a frequency of 100 MHz, but data mismatches are observed for lower frequencies (for example 50 MHz and 25Mhz ).

Solution

As a temporary workaround, when using the lower frequencies for QSPI interface, please change the following line:

#define xqspips_read(addr) readl_relaxed(addr)
This line needs to be replaced with:
#define xqspips_read(addr) readl(addr)

The root cause of this issue is currently being investigated.
