To reduce the differences between these file name the enabling
device function in the directory `src/mainboard` uniformly
`mainboard_enable` [1].
Thanks to the awesome help of gnomon and BlastHardcheese in the
IRC channel #sed on <irc.freenode.net>. gnomon came up with the
following command to do the actual work.
$ cd src/mainboard
$ for f in */*/mainboard.c ; \
> do src="$(awk '/\.enable_dev = /{v=$NF; sub(/,$/,"",v); print v}' "$f")" ; \
> [[ -z $src ]] && continue ; \
> printf '%s\n' "g/${src}/s/${src}\([,(]\)/mainboard_enable\1/p" w | ed -s "$f" ; \
> done
`src/mainboard/digitallogic/msm586seg/mainboard.c` and
`src/mainboard/technologic/ts5300/mainboard.c` had to be adapted
manually as no comma was used separating the struct members.
And with the following statement, gnomon is even more likable!
My pleasure entirely. Good luck with coreboot; I'm a big fan of the project.
