There are uniform, non-uniform and flexible erase flash configurations. The non-uniform erase types, are the erase types that can _not_ erase the entire flash by their own. As the code was, in case flashes had flexible erase capabilities (support both uniform and non-uniform erase types in the same flash configuration) and supported multiple uniform erase type sizes, the code did not sort the uniform erase types, and could select a wrong erase type size. Sort the uniform erase mask in case of flexible erase flash configurations, in order to select the best uniform erase type size. Uniform, non-uniform, and flexible configurations with just a valid uniform erase type, are not affected by this change. Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn. Non uniform erase tested on sst26vf064B-104i/sn.
