CONFIG_SPI does not exist in Kconfig in the first place, so the

Actually, some defconfigs such as socfpga_*_defconfig define
CONFIG_DM_SPI_FLASH=y, but it never appears in the .config file
because of this wrong dependency.

On the other hand, all the Tegra boards enable DM_SPI_FLASH because

   config DM_SPI_FLASH
           default y

silently ignores the dependency.
Unfortunately, this style of CONFIG definition is abused everywhere
in U-Boot, so we easily miss such a wrong dependency.

Applied to u-boot-dm/next, thanks!

Do you plan to release a v2015.04.1 stable release at some time? Then please add this patch to this version. As it fixes SPI NOR flash on SoCFPGA.

Thanks,
Stefan
