Subject: [PATCH u-boot-marvell v2 3/3] arm: mvebu: Enable CONFIG_SPL_SYS_NO_VECTOR_TABLE for 32-bit mvebu
Date: Wed,  6 Apr 2022 16:20:20 +0200	[thread overview]
Message-ID: <20220406142020.24984-3-pali@kernel.org> (raw)
In-Reply-To: <20220406142020.24984-1-pali@kernel.org>

U-Boot SPL is on 32-bit mvebu executed by the BootROM. And BootROM expects
that U-Boot SPL returns execution back to the BootROM. Vectors during
execution of U-Boot SPL should not be changed as BootROM does not expect it
and uses its own vectors. So do not overwrite vectors in SPL build.
