 * \brief DataFlash test.
 *
 * This module test the dataflash memory among the supported memory (see drv/dataflash.h
 * for more detail).
 * To test memory we fill one buffer with casual char, and write it in different
 * part of memory. After every write we read the data that we have been write
 * and compare this with test buffer, checking if write and read command work
 * correclty. We also check if driver work properly when we make a write out the
 * limit of memory size.
 *
 * Note: dataflash driver use a kfile interface, so for write/read test
 * we use a kfile_test module that perform some generic test.
