Subject: [PATCH v4 03/20] x86/efi: Replace CONFIG_CMDLINE_OVERRIDE by CONFIG_CMDLINE_FORCE
Date: Fri,  2 Apr 2021 15:18:04 +0000 (UTC)	[thread overview]
Message-ID: <76542a49b685ddb41894fd53feb250fcec731b01.1617375802.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1617375802.git.christophe.leroy@csgroup.eu>

During boot, x86 uses EFI driver. That driver is also used
by ARM.

In order to refactor the command line processing in that driver
in a following patch, rename CONFIG_CMDLINE_OVERRIDE by
CONFIG_CMDLINE_FORCE on the x86 in order to be similar
to ARM (and most other architectures).
