1. I git reset to this commit: feb5a02f869d
2. Your patch has been applied(https://patchwork.ozlabs.org/patch/1146377/)
3. Apply my current patch set
4. Include/uncmd_uncmd_spl.h file is deleted as follows:
- # undef CONFIG_DM_SPI
- # undef CONFIG_DM_SPI_FLASH
5. In include/configs/T208xQDS.h  file:
+/* SPI Flash Configs */
+ # if defined (CONFIG_SPL_BUILD)
+ # undef CONFIG_DM_SPI
+ # undef CONFIG_DM_SPI_FLASH
+ # undef CONFIG_SPI_FLASH_MTD
+ # endif
6. Make menuconfig:
Configuration 
CONFIG_SPL_DM_SPI = y
CONFIG_SPL_DM_SPI_FLASH = y
7. Compilation errors still occur:
LD      spl/lib/built-in.o
  LD      spl/u-boot-spl
drivers/built-in.o: In function `ofnode_read_u32':
