Subject: [PATCH u-boot-marvell v2 2/3] arm: Do not compile vector table when SYS_NO_VECTOR_TABLE is enabled
Date: Wed, 6 Apr 2022 16:20:19 +0200 [thread overview]
Message-ID: <20220406142020.24984-2-pali@kernel.org> (raw)
In-Reply-To: <20220406142020.24984-1-pali@kernel.org>
Vector table is not used when SYS_NO_VECTOR_TABLE is enabled.
So do not compile it and reduce image size.
