first, this related to CONFIG_FASTBOOT_FLASH:

when this code was added (in commit c0aebb3) the comment was in the correct place, unfortunately, subsequent changes have moved the comment to the wrong line.....
i don't think CONFIG_FASTBOOT_FLASH ever makes use of being assigned a numeric value, does it? the top-level README file certainly doesn't seem to think so:
CONFIG_FASTBOOT_FLASH The fastboot protocol includes a "flash" command for writing the downloaded image to a non-volatile storage device. Define this to enable the "fastboot flash" command.
and it's never used in that context as far as I can tell:
$ grep -rw CONFIG_FASTBOOT_FLASH * common/Makefile:ifdef CONFIG_FASTBOOT_FLASH drivers/usb/gadget/f_fastboot.c:#ifdef CONFIG_FASTBOOT_FLASH drivers/usb/gadget/f_fastboot.c:#ifdef CONFIG_FASTBOOT_FLASH drivers/usb/gadget/f_fastboot.c:#ifdef CONFIG_FASTBOOT_FLASH include/configs/kc1.h:#define CONFIG_FASTBOOT_FLASH include/configs/sniper.h:#define CONFIG_FASTBOOT_FLASH include/configs/bcm28155_ap.h:#define CONFIG_FASTBOOT_FLASH include/configs/sunxi-common.h:#define CONFIG_FASTBOOT_FLASH include/configs/dra7xx_evm.h:#define CONFIG_FASTBOOT_FLASH README: CONFIG_FASTBOOT_FLASH $
and second, just below that in common/Makefile (almost at the end):
# We always have this since drivers/ddr/fs/interactive.c needs it obj-$(CONFIG_CMDLINE) += cli_simple.o
obj-y += cli.o obj-$(CONFIG_CMDLINE) += cli_readline.o
apart from the typo in that comment (should be "ddr/fsl", not "ddr/fs"), why does the comment insist that "We always have this" when that file is conditionally compiled? What does cli_simple.o have to do with that ddr-related source file? one suspects this could be simplified as:
obj-y += cli.o obj-$(CONFIG_CMDLINE) += cli_simple.o cli_readline.o
or something equally simple. or am i missing something?
