Subject: [PATCH v2 08/13] mips/kexec: refactor for kernel/Kconfig.kexec
Date: Mon, 19 Jun 2023 10:57:56 -0400	[thread overview]
Message-ID: <20230619145801.1064716-9-eric.devolder@oracle.com> (raw)
In-Reply-To: <20230619145801.1064716-1-eric.devolder@oracle.com>

The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.
