Subject: [Buildroot] [PATCH v2 2/5] package/pkg-utils: add KCONFIG_APPEND_OPT
Date: Fri, 14 Oct 2022 08:58:57 +0200	[thread overview]
Message-ID: <20221014065900.3311604-3-angelo@amarulasolutions.com> (raw)
In-Reply-To: <20221014065900.3311604-1-angelo@amarulasolutions.com>

This macro can be used to append a value to a previously configured
option where the intent is to join the old value with the new one.
