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.
