Thanks for posting v4 for spi-nor support.
Tested the series above u-boot-spi/master on HiFive Unleashed and was able to verify it for both spi-nor and mmc
Additionally just confirmed the opcodes nor is configured with post spi_nor_scan:
======================================================
[QUAD mode in dt with spi-tx-bus-width: <4>]
 pp opcode      = 0x34 [QUAD MODE]
 read opcode  = 0x6c  [QUAD MODE]
 erase opcode = 0x21  

SPI-NOR:
1. erase entire flash: Pass
2. write entire flash: Pass
3. read entire flash: Pass
4. cmp 32MiB read back data: Pass
5. MMC: Booted Linux and dtb from mmc (so as to confirm data integrity from mmc)
=================================================================
[SPI MODE in dt with spi-tx-bus-width: <1>  ]
pp opcode     = 0x12 [SPI MODE]
read opcode  = 0xc   [SPI MODE]
erase opcode = 0x21

SPI-NOR:
1. erase entire flash: Pass
2. write entire flash: Pass
3. read entire flash: Pass
4. cmp 32MiB read back data: Pass 
5. MMC: Booted Linux and dtb from mmc (so as to confirm data integrity from mmc)
