For chip/block/sector erase operations, spi_write_enable is integrated into those operations;
I meant spi_write_enable is called explicitly.
for byte program, spi_write_enable is not integrated.
Whether preop will be sent or which preop will be sent before BYTE_PROGRAM is specified in struct OPCODES.
Maybe whether to call spi_write_enable in spi_xxx_erase should be flash bus specific.
