rather than go to the trouble of whipping up a wiki page, i can present this in a short post to the list. here's the list of what my script identified as "badref selects" -- those identifiers for which there is a Kconfig line of the form:
select X
where there is no corresponding:
config X
the entire list:
BOOTM_LINUX CONFIG_EHCI_HCD_INIT_AFTER_RESET CONFIG_MPC8xx_WATCHDOG CPU_ARM926EJS1 CRC32 GPIO MSCC_BITBANG_SPI_GPIO SPL_DISABLE_OF_CONTROL VEXPRESS_CLK
first, the two with the "CONFIG_" prefix are obvious typos which should have those prefixes removed.
as for the rest, as one example, consider "CRC32":
$ git grep "select CRC32" cmd/Kconfig: select CRC32 cmd/Kconfig: select CRC32 drivers/mtd/ubi/Kconfig: select CRC32 fs/btrfs/Kconfig: select CRC32C $
there is no matching "config CRC32" anywhere, although there is:
include/image.h:# define CONFIG_CRC32 /* FIT images need CRC32 support */
in any event, others are welcome to decide what to do about that short list of suspicious "select" directives. i am not trying to be annoying, i am merely succeeding.
