It is observed that it gets configured with Serial Input Page program by the end of spi_nor_scan. Using the post bfpt fixup hook we prioritize the page program settings to use quad input page program (opcode:0x34) over serial input page program (opcode: 0x12). The patchset is tested on Linux 5.7-rc3.
