Subject: [PATCH v1 0/2] update is25wp256d page write capabilities  

HiFive Unleashed A00 board has is25wp256d snor chip. 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 5.7.0-rc5.

Changelog:
===============================
V1:
-Moved SPI_SIFIVE from defconfig to Kconfig.socs for SOC_SIFIVE.
 Retained it's configurability using "imply" instead of "select"

V0: Base version patch (Tested on 5.7.0-rc3).



Sagar Shrikant Kadam (2):
  riscv: defconfig: enable spi nor on Hifive Unleashed A00 board.
  spi: nor: update page program settings for is25wp256 using post bfpt
    fixup
