Subject: [PATCH 1/4] riscv: vmlinux-xip.lds.S: remove .alternative section
Date: Thu, 11 May 2023 22:12:08 +0800	[thread overview]
Message-ID: <20230511141211.2418-2-jszhang@kernel.org> (raw)
In-Reply-To: <20230511141211.2418-1-jszhang@kernel.org>

ALTERNATIVE mechanism can't work on XIP, and this is also reflected by
below Kconfig dependency:

RISCV_ALTERNATIVE
	...
	depends on !XIP_KERNEL
	...

So there's no .alternative section at all for XIP case, remove it.
