The function sector_erased() is modified to not use pointer access, but to use the correct accessor functions. This fixes a problem on the t3corp board with the Xilinx DS617 flash chips. Here a board specific accessor function is needed to read from flash in 32bit mode. This patch enables such an operation mode.
