Get rid of the static initialization of the flash parameters and init them when parsing SFDP. Generated a 256 Kbyte random data and did an erase, write, read back and compare test. The flash uses for reads SPINOR_OP_READ_1_4_4 0xeb, for erases SPINOR_OP_BE_4K 0x20, and for writes SPINOR_OP_PP 0x02.
