[U-Boot] [PATCH 3/3] MAKEALL: fix boards_by_field function

Hello Albert.

OK. It's clear now.

I re-wrote like follows:


boards_by_field()
{
	field=$1
	regexp=$2

	awk '($1 !~ /^#/ && $'"$field"' ~ /^'"$regexp"'$/) { print $7 }' \
		boards.cfg
}

boards_by_arch() { boards_by_field 2 "$@" ; }
boards_by_cpu()  { boards_by_field 3 "$@" ; boards_by_field 3 "$@:.*" ; }
boards_by_soc()  { boards_by_field 4 "$@" ; }



Is this good enough?




BTW, I think these function names are misleading.


We want to get the 7th field (Target),
not 6th field (Board Name) of boards.cfg
by these functions.


So I think we should rename

s/boards_by_field/targets_by_field/
s/boards_by_arch/targets_by_arch/
s/boards_by_cpu/targets_by_cpu/
s/boards_by_soc/targets_by_soc/
