[U-Boot] [PATCH v3 1/3] spi: Kconfig: Enable SPI_SUNXI for SUNXI
SPI_SUNXI driver is fully dm-aware and the Allwinner architecture kconfig would have logic to enable the DM_SPI. So, select default spi sunxi driver for sunxi architecture.

You also need to set CONFIG_SPI_FLASH since it's not set by default and CONFIG_SPI_FLASH_WINBOND depends on CONFIG_SPI_FLASH.

You also need to set CONFIG_SPI_FLASH since it's not set by default and CONFIG_SPI_FLASH_WINBOND depends on CONFIG_SPI_FLASH.
SPI_FLASH would select if DM_SPI_FLASH set. we have a patch on ML.
Winbond seems to boards specific flash, so I've mark it to board config itself.
