Speedup version

(8) for 4K pagesize nand && 80MHz && speedup version:
can not work!!!

(9) for 4K pagesize nand && 70MHz && speedup version:
same as 64MHz.

(10) for 4K pagesize nand && 78MHz && speedup version:
actually is : "Nand clock set to 77142800"
can not work!!!

==>>
the max speed is 64MHz && speed up verion:
write ~= 3600 KiB/s ~= 3.5 MB/s
read ~= 13000 KiB/s ~= 12.5MB/s
