There are many "force an error till we get a good number" comments in
target/board files. This refers to the use-case where a config script
sets _CPUTAPID to 0xffffffff (which presumely gets overridden later):
if { [info exists CPUTAPID ] } {
set _CPUTAPID $CPUTAPID
} else {
# Force an error until we get a good number.
set _CPUTAPID 0xffffffff
}
However, the same comment was also copy-pasted in many files which do
_not_ set _CPUTAPID to 0xffffffff, where the comment doesn't make any
sense at all. Drop those comments. Also, add one missing comment, and
fix small whitespace and grammar issues.
