Correct, it should build even with CONFIG_SYS_NO_FLASH.

The patch is applied.

FWIW, how about putting CONFIG_SYS_NO_FLASH prior to <config_cmd_
default.h>?

No. In U-Boot, in general, drivers should be predefined through
configs/<boardname>.h. If we don't use CFI driver, just disable
it in top-level board config file. This is to avoid #ifdef mess,
and prevent the drivers from being clobbered.
