[PATCH 3/3] sh/boot: Use POSIX "$((..))" instead of bashism "$[...]"

From: Geert Uytterhoeven
Date: Thu Jun 13 2013 - 09:11:34 EST


According to the bash 4.1 manpage, "$[...]" is deprecated, and will be
removed in upcoming versions of bash.
Hence replace the bash-specific "$[...]" by POSIX "$((..))" for arithmetic
expansion, which also allows to drop the forced use of bash.
