From 19e6dd0b6196f6675c1ed9efac219cb724c018e6 Mon Sep 17 00:00:00 2001 From: Eric DeVolder Date: Wed, 12 Jul 2023 12:15:37 -0400 Subject: loongarch/kexec: refactor for kernel/Kconfig.kexec 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.
