Replace Altera EPCS4 with M25P40

Hello folks, We currently use epcs4 as altera FPGA's configuration device, but the price of epcs4 is quite expensive. I found that ST's m25p40 can be used to replace the epcs4 in this link...

You didn't read the M25P40 datasheet thoroughly. It's also supporting the 0xAB instruction. If I remember right, both chips have even the same manufacturer ID.
